Express As with two-dimensional problems, a free-body diagram is the first step in solving three-dimensional equilibrium problems. For the free-body diagram, it is important to identify the appropriate reaction forces and couple moments that act in three dimensions. At a support, a force arises when translation of the attached member is restricted and a couple moment arises when rotation is prevented Hints Ay. A | Figure 1 ] of 1 Submi Part B B CExplanation / Answer
The tension force supported by cable DE is 0.
that tension is zero because the shaft at point A is loose so movement in the x direction is permitted.
Since Ay is the only force in the y-direction, Ay = 0
The only forces in the z-direction are Az, W_b and F
So 0 = Az - W_b - F
Az = W_b + F
Az = 5.40 + 1.80
Az = 7.2 lb
Answer:
Ay = 0, Az= 7.2 lb.
