Part A

Determine the force in members CD of the truss, and state if the member is in tension or compression. Take P = 1675 lb (Figure 1)

Express your answer to three significant figures and include the appropriate units. Assume positive scalars for members in tension and negative scalar for members in compression

Part B

Determine the force in members HI of the truss, and state if the member is in tension or compression. Take P = 1675 lb

Part C

Determine the force in members CJ of the truss, and state if the member is in tension or compression. Take P = 1675 lb.
