The paper rolls, shown in the figure below, are 0.9 m OD x 0.22 m ID x 3.23 m long and have a density of 984 kg/m3 . The rolls are transferred from the machine conveyor (not shown) to the forklift truck by the V-linkage of the off-loading system, which isrotated through 90o by an air cylinder. The paper then rolls onto the waiting forks of the truck.

Question: Assume that the crank arm is a solid rectangularsection. Working on a factor ofsafety of 5, determine suitable dimensions for this arm. Select (providing reasons) a material 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 the arm cross section. Also determine the position of the neutral axis. Illustrate the stress distribution and neutral axis on a sketch of the section.

As shown in the figure (Figure 1) , a superball with mass m equal to 50 grams is dropped from a height of hi=1.5m . It collides with a table, then bounces up to a height of hf=1.0m . The duration of the collision (the time during which the superball is in contact with the table) is tc=15ms . In this problem, take the positive y direction to be upward, and use g=9.8m/s2 for the magnitude of the acceleration due to...

The radius of the roll of paper shown in the figure is 7.6 cm and its moment of inertia is I = 2.9 × 10-3 kg·m2. A force of 2.9 N is exerted on the end of the roll for 1.1 s, but the paper does not tear so it begins to unroll. A constant friction torque of 0.11 m·N is exerted on the roll which gradually brings it to a stop. Assume that the paper's thickness is negligible. (a)...
