Question 5 P 0.8 m A rigid uniform square block of mass m = 60 kg is resting on the ground as shown above. A force P is applied to the block at 0.8 m above the ground. The coefficient of kinetic friction between the ground and the block is given by uk = 0.2. It can be shown that the free-body diagram for the situation above is as given below, where F is the friction, N is the normal...

A crane is made from a uniform rigid boom of length L = 30m and weight w = 400N. The boom is sup- ported by a frictionless hinge at its lower end. Its upper end is attached to a support cable which is fas- tened behind the boom at the same horizontal level as the hinge. Adjusting the length of the support / cable adjusts the angle of the boom. In a particu- 7/TTI IN lar application, the crane is...
