Two space trusses are used to equally support the uniform sign of mass M. Determine the force developed in members AB, AC, and BC of truss ABCD and state if the members are in tension or compression. Horizontal short links support the truss at joints B and D and there is a ball-and-socket joint at C.

Given:

M = 50 kg g = 9.81m/s2

a = 0.25 m

b = 0.5 m

c = 2 m
