Chapter 3.3, Problem 54P
The pin A, which connects the 200-kg steel beam with center of gravity at G to the vertical column, is welded both to the beam and to the column. To test the weld, the 80-kg man loads the beam by exerting a 300-N force on the rope which passes through a hole in the beam as shown. Calculate the torque (couple) M supported by the pin.

The T-bar AEBF is connected to rod CD, with the joint at F being equivalent to a slider bearing. The supports at A and C are slider bearings, and thrust bearings are found at B and D. The two applied forces, which act at the midpoint of the arm EF, are parallel to the y- and z-axes, respectively. Neglecting the weights of the members, draw the FBDs for the entire structure, the T-bar, and rod CD. Determine the total number of unknowns.
What's the the horizontal component of the reaction force from the pin at ?
