PROBLEM 2 (35 pts)
A bar of negligible mass is supported by a ball and socket support at A, a ROLLER support at C, and the cable BD. Point C has coordinates (8, 0, 0), Point B is at the midpoint of the bar, so its coordinates are (4, 1.5, 0), and Point D lies in the x-z plane. The force vector F = -50 k (lb).
a) Draw the free-body diagram of bar ABC.
b) Find the position vector rba.
c) Write the equilibrium equations based on the FBD drawn in part a.
d) Find the following: Reactions at Point A, Reactions at Point B, Tension in Cable BD.
