Fatigue Analysis of the FSAE Vehicle's Front Wheel Hub
Abstract: This study illustrates the design and analysis of the FSAE vehicle's front wheel hub. Because wheel hubs are subjected to cyclic loads on a continuous basis, there is a risk of fatigue, which leads to material failure. The start and spread of cracks in a material as a result of cyclic loading is known as fatigue. The brake discs could not be easily removed since the disc is positioned between …

Organophilicization of Bentonite by HDTMA+ and TMPA+ Cations for Sorption of 2,4-Dichlorophenol (2,4-DCP) in Aqueous Solution
Abstract: Bentonite (Bt) was converted to organoclays by intercalation of cationic surfactants into its interlayer space. Two types of organoclays were synthesized from HDTMA and TMPA at 100% CEC, and the adsorbents were characterized by FTIR, XRD and SEM. The adsorption capacities of Bt and the organoclays for the removal of 2,4-dichlorophrnol (2,4-DCP) from aqueous solutions were tested under different conditions. Two adsorption isotherm models (Langmuir and Freundlich isotherms) were used …
