Question

A 60-lb sign is supported by a pin and bracket at A and by a cable BC. Determine the reaction at A and the tension in the cable.

a. Reaction at A = 60 lb, Tension in cable BC = 0 lb
b. Reaction at A = 30 lb, Tension in cable BC = 30 lb
c. Reaction at A = 40 lb, Tension in cable BC = 40 lb
d. Reaction at A = 50 lb, Tension in cable BC = 50 lb

Answer 1

The reaction at point A is the combined weight of the strut and the sign, which is 600.0 N. The tension in the cable BC is also 600.0 N.

Step-by-step explanation:

To determine the tension in the cable and the force at the h`inge of the strut, we can analyze the forces acting on the system. In this case, we have a uniform strut with a weight of 400.0 N and a sign weighing 200.0 N hanging from the end of the strut.

The strut is supported by a hi`nge at the wall and a cable attached to the wall. The weight of the sign is applied at the very end of the strut.
