Determine the force in member CD of the truss and state if the member is in tens

Question

Determine the force in member CD of the truss and state if the member is in tension or compression . Take P = 1840 lb. Express your answer to three significant figures and include the appropriate units. Assume positive scalars for members in tension and negative scalars for members in compression. Determine the force in member HI of the truss and state if the member is in tension or compression . Take P = 1840 lb. Express your answer to three significant figures and include the appropriate units. Assume positive scalars for members in tension and negative scalars for members in compression. Determine the force in member CH of the truss and state if the member is in tension or compression . Take P = 1840 lb. Express your answer to three significant figures and include the appropriate units. Assume positive scalars for members in tension and negative scalars for members in compression.

Explanation / Answer

Force member HG: 1125 lb Force member HE: 3750 lb Force member DE: 3375 lb Force member CD: -3375 lb Force member HC: -5625 lb Force member HI: 6750 lb ^those are all the forces I have so far. Please help me find the rest.
