Determine the reactions at A and the forces in the pin at B.

The smooth uniform rod AB is supported by a ball-and-socket joint at A, the wall atB, and cable BC. Determine the components of reaction at A, the tension in the cable,and the normal reaction at B if the rod has a mass of 20 kg. Once you have your solution examine the reaction force at A and determine if it points in the direction of the member AB

Determine the reaction force at C

The smooth uniform rod AB is supported by a ball-and-socket joint at A, the wall at B, and the cableBC. Determine the components of reactions at A, the tension in the cable, and the normal reaction at Bif the rod has a mass of 20 kg. Provide a free-body-diagram.

Because of long-term loading from the 900-N tension in the power line, the uniform utility pole has developed a 5° lean. If the mass per unit length of the 9-m pole is 24 kg/m and the mass of the lamp fixture is negligible, determine the reactions at the ground support A. (Moment of Force, Forces along x and Forces along y)

A rope passes over a frictionless pulley at D, as shown. The cylinder weighs 300 lb. Determine the ension in the rope and the horizontal and vertical components of the reaction at the hinge support A. Neglect the weight of the bar AC. В 5ft

The two couples act at the midpoints of bars AB and BD. Determine the components of the reactions and the magnitudes of the reactions at A, B and D. Neglect the weights of the members. Draw an FBD of the system as a whole and an FBD of the bar AB, in which you assume the direction of all forces at all pin connections in the positive x and positive y directions for consistency with the options in the questions. At which one of the following points is there an error in the free-body diagram?
