A 54 kg skip attached to a steel rope on a crane is used to hoist bricks from the ground to the top of a construction site. The steel rope is wound onto a lifting drum with a diameter of 700 mm which rotates. The lifting drum is situated on the top floor. Calculate the torque (in N.m) on the lifting drum, to lift 20 bricks weighing 150 kg, ignoring the weight of the steel rope.

A simple log bridge in a remote area consists of 2 parallel logs with planks across them. The log has an average diameter of 300 mm. A truck moves slowly across the bridge, which spans 2.5 m. Assume that the weight of the truck is equally distributed between the 2 legs. Because the wheel base of the truck is greater than 25 m. Only 1 set of the wheels is on the bridge at a time. Thus, the wheel load on one log is equivalent to a concentrated load acting at any position along the span. In addition, the weight of 1 log and the plank it supports in equivalent to a uniform load of 65 kN/m acting on the log. 1. Determine the max permissible wheel load W based upon the allowable bending stress of of 7MPa. 2. Determine the max permissible wheel load W based upon the allowable shear stress of of 0.75MPa. 3.
