The paper rolls, shown in the figure below, are 0.9 m OD x 0.22m ID x 3.23 m long and have a density of 984 kg/m3 . The rolls aretransferred from the machine conveyor (not shown) to the forklifttruck by the V-linkage of the off-loading system, which isrotatedthrough 90o by an air cylinder. The paper then rolls onto thewaiting forks of the truck.
Question: Assume that the crank arm is a solidrectangularsection. Working on a factor ofsafety of 5, determinesuitable dimensions for this arm. Select (providing reasons) amaterial for this crank arm. b) Due the misalignment of the loading(refer 2c), the force is offset from the loading axis by 15o .Determine the bending stresses at each of the four corners of thearm cross section. Also determine the position of the neutral axis.Illustrate the stress distribution and neutral axis on a sketch ofthe section.
