A lightweight wheel has the potential of providing better manoeuvrability and overall control during high performance operation. In this study, a Finite Element Model (FEA) was implemented to investigate the dynamic cornering fatigue of the newly designed lightweight racing wheel. Due to the reason that the test was performed in a worst-case scenario and the specimens were required to achieve the minimum life cycles, out of the 36 specimens, the result has shown that only 12 specimens were able to pass the test. Based on the analysis, the specimens highlighted in green were those that could pass the test. It can be noted that those passed specimens were having 7 and 8 spokes. Conclusively, the cornering fatigue test shows that the spoke is vital in affecting the wheels' performance. For future studies, it is recommended that experimental studies are conducted.","PeriodicalId":475560,"journal":{"name":"Journal of Advanced Research in Applied Mechanics","volume":"45 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141011680","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Kenaf fiber, derived from the Hibiscus cannabinus plant, presents a promising avenue for enhancing the mechanical and energy absorption properties of composite tubes. This study focuses on the fabrication of composite tubes using a combination of kenaf fiber and epoxy resin. The composite tubes were then subjected to compressive testing to evaluate their energy absorption performances. The fabrication process involved the impregnation of kenaf fibre with epoxy resin, followed by winding and curing to form composite tubes. Different configurations of kenaf fiber content were utilized to investigate their impact on the structural integrity and energy absorption capabilities of the tubes. Compressive testing was conducted to assess the energy absorption behaviour under axial loading conditions. The results revealed that the incorporation of kenaf fiber significantly influenced the energy absorption capabilities of the composite tubes. Higher kenaf fiber content demonstrated improved energy absorption performance, showcasing the potential of kenaf fiber as an efficient energy-absorbing reinforcement. The findings of this study offer valuable insights into the use of sustainable and renewable resources, such as kenaf fiber, in enhancing the mechanical and energy absorption properties of composite structures, thereby contributing to the development of eco-friendly and high-performance materials.","PeriodicalId":475560,"journal":{"name":"Journal of Advanced Research in Applied Mechanics","volume":"301 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141012563","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This model is based on the concrete compressive strength (fc), concrete cover (Cc), and bar diameter (db), which are considered the most influential parameters on the bond response between the reinforcement and surrounding concrete. The regressed model shows a quite accurate prediction of the bond behaviour of HCFA, particularly those with high strength.

However, the inability to regulate the speed of the load can present significant challenges in terms of machinery maintenance and energy consumption. This paper simulates and proposes a solution for the induction motor speed control which implements an inverter consisting of a Variable Frequency Drive (VFD) system using Matlab software. The aim is to analyze the impact of adding a VFD circuit to a three-phase motor system in terms of its starting current and speed. A VFD is highly beneficial for electric motors as it can optimize motor speed based on the specific requirements or desired speed settings. The method involves the uses of power electronic devices such as IGBT components. By controlling the duration of on-off time and the width of the pulse, a desired frequency can be obtained. By varying the frequency of the power supply to the motor, the synchronous speed can be controlled to the required value. Simulation results demonstrate that a circuit with a variable frequency drive (VFD) drastically reduces starting current, effectively minimizing power losses during motor start-up. Comparative analysis reveals that the VFD, the starting current surge to approximately 9A, a significant improvement compared to the 50A spike observed without the VFD. Additionally, the motor speed remains consistent in both scenarios, suggesting that the VFD does not adversely affect the motor's speed, which is 1490 rpm, while maintaining the voltage and current supplied to the load. The findings highlight the benefits of using a VFD in the motor system to improve energy efficiency and minimize power losses during operation.","PeriodicalId":475560,"journal":{"name":"Journal of Advanced Research in Applied Mechanics","volume":"27 S1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141011344","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Chemical stabilization was proven to be an effective method to stabilize the problematic soil. To date many additives like Ordinary Portland Cement, fly ash, lime and other alternatives binder has been applied to improve the compressive strength of the problematic soil. The study describes the effect of compressibility of improved peat soil using waste from industrial such as Mg-rich synthetic gypsum (MRSG) by-product and concrete waste aggregate from institution laboratory waste that can be used to improve the settlement problem of the Gebeng, Malaysia peat soil. The test was conducted at varying percentages of MRSG and concrete waste aggregate additives at 5%, 10%, 15%, and 20% by weight of the soil. The unconfined compression strength (UCS) test was determined to obtain the optimum strength ratio and the data revealed that the optimum ratio of gypsum and concrete waste required to enhance the properties of peat soil were at 5% gypsum, 10% concrete waste, and 10% concrete waste combined with 10% gypsum. Coefficient of consolidation, compression index, and coefficient of volume compressibility were obtained by oedometer test for both untreated and treated peat soil with additives. The compression ratio of the peat soil indicated the peat was very compressible and however, the compression ratio was observed at very slightly compressible once the soil stabilized with the optimum ratio mix. The results indicated that the combination of these two additives improved the compressibility characteristics of peat soil. This research will contribute to the fundamental behaviour of geotechnical problematic soil in Malaysia which results in sustainable approach by recycling the industrial and institutional waste, Mg-rich gypsum and concrete waste aggregate for soil improving instead of implementing soil removal replacing techniques.","PeriodicalId":475560,"journal":{"name":"Journal of Advanced Research in Applied Mechanics","volume":"317 9","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141012308","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study investigates the performance of combined banana peels and banana pith as dual natural plant-based coagulants for turbidity removal. Banana peel powder solution (BPPS), banana pith juice (BPJ), and the combination of BPPS and BPJ were prepared via several steps, including drying, grinding, sieving, mixing, and crushing. The three types of coagulant produced were tested in a series of jar test experiments under the effects of different dosages, pH, and mixing speeds. The scanning electron microscopy images of banana pith show the formation of multicellular fibers, while irregular shapes and micro-rough crate-like pores are formed in banana peels, which contribute to the adherence of contaminants. Jar test results revealed the highest turbidity removal of 97.3, 98.0, and 99.1% was attained by using 60, 80, and 20:20 mg/L of banana peel powder solution, banana pith juice, and a combination of banana peel powder solution and banana pith juice coagulant dosage, respectively, with an optimum pH of 2, at a rapid mixing rate of 180 rpm (5 minutes) and a slow mixing of 60 rpm (20 minutes). Significantly, this removal was attributed to the presence of proteins and polysaccharides in both banana peels and pith. The findings suggested that banana peels and pith are applicable as natural plant-based coagulants for turbidity removal in the water treatment process and a potential substitute for conventional coagulants. In addition, the combined banana peels and banana pith coagulant prove to be more efficient than the existing banana peels and banana pith coagulant.","PeriodicalId":475560,"journal":{"name":"Journal of Advanced Research in Applied Mechanics","volume":"239 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141012786","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using natural coagulants in water treatment provides a safer and more sustainable method. Insufficient research in this field hinders a thorough comprehension of the ideal circumstances, dosage, and potential impacts of Carica papaya dry seed coagulation on pollutant elimination in wastewater. Therefore, the investigation of the extraction procedure for coagulants derived from dried Carica papaya seeds is essential to establish a reliable and efficient method suitable for use in wastewater treatment facilities. The number of experiments were conducted to accomplish the objective of this study. The experiment utilised textile effluent from an industrial area in Parit Raja, Johor as the wastewater sample. The Carica papaya seeds were ground into a powder and then mixed with Sodium Chloride (NaCl) and distilled water to create a coagulant solution. COD, turbidity, pH, and settling depth were measured to assess the effectiveness of Carica papaya seeds in treating the effluent sample. At a Carica papaya seed coagulant dosage of 2.0 mL with a NaCl concentration of 1.5 M, the optimal COD reduction and turbidity removal efficacy were at 20.95 % and 23.00 %, respectively. This study shows that among 5 different concentration solvent, 1.5M NaCl is most optimum concentration condition demonstrated. Moreover, the research represents the significant potential of Carica papaya seed powder as a natural coagulant for treating wastewater that contains textile colouring agents. In conclusion, the research demonstrated that dried Carica papaya seeds possess the potential to serve as a natural coagulant in wastewater treatment procedures, thereby presenting a safer and more ecologically sustainable alternative.

However, the current application of RSM is restricted to a few responses and updating parameters, and unresolved issues persist, including symmetrical damage location and false damage detection. In this study, a new RSM approach is introduced, using FRF curvature as the response. The effectiveness of the proposed method is demonstrated through an experimental modal analysis of a free-free aluminium beam, employing four different Design of Experiment (DOE) techniques: a minimum-run resolution V (CCDmrv) design and a half-fractional (CCDhalf) design using Central Composite Design (CCD), Box-Behnken design (BBD), and D-optimal design.
