See our solution for Question 5P from Chapter 5 from Hibbeler's Engineering Mechanics.
We are asked to draw free-body diagrams for the problem 5-32, 5-33, 5-35, and 5-36.
Part (a)
The free-body diagram of the boom in problem 5-32 is drawn below.

Here, ${A_x}$ is the reaction force at point A in the x-axis direction, ${A_y}$ is the reaction force at point A in the y-axis direction, ${F_{BC}}$ is the force in cable BC.
Part (b)
The free-body diagram of the jib cranein problem 5-33 is drawn below.

Here, ${A_x}$ is the reaction force at point A in the x-axis direction, ${B_x}$ is the horizontal reaction force at point B, ${B_y}$ is the vertical reaction force at point B, $W$is the weight of crane.
Part (c)
The free-body diagram of the smooth pipein problem 5-35 is drawn below.

Here, ${N_A}$ is the reaction force at point A, ${N_B}$ is the reaction force at point B, ${N_C}$ is the reaction force at point B.
Part (d)
The free-body diagram of the beamin problem 5-36 is drawn below.

Here, ${F_A}$ is the reaction force at the left end of the beam, ${F_B}$ is the reaction force at the right end of the beam.
