A cantilever beam is being loaded. Determine the moment at point o and the vertical reaction at the same point.

Beam AB has a negligible mass and thickness, and it supports the 200 kg uniform block. It is pinned at A and rests on the top of a post, having a mass of 20 kg and negligible thickness. Determine the two coefficients of static friction at B and C so that when the magnitude of the applied force is increased to P = 300 N, the post slips at both B and C simultaneously. A 1.5 m t-1.5 m- 1 m 0.75 m

The hoist supports the 150-kg engine. Determine the force in members DB and FB. Also determine the reactions on the floor at A and C. m m 2 m BO E 2 m 1m

A concentrated live load of 15 kN and a uniform live load of 4 kN/m are to be placed on the beam. The beam has a weight of 1.75 kN/m. Assume the support at A is a roller and B is pinned. *C is not an internal pin. Determine the following: a. the maximum vertical reaction at support A b. the maximum positive moment at point C. B 10 ft 10 ft 15 ft
