The space truss shown below is supported by ball-and-socket joints at A, B, and E. Set F = {900 j} N. Hint: The support reaction at E acts along member EC.
Determine the force in the ALL members (AD, BD, CD, AC, BC, & EC) of the truss and state if the member is in tension or compression. Express your answer to three significant figures and include the appropriate units. Enter negative value in the case of compression and positive value in the case of tension.
