Determine the force in members $KJ,KD,$ and $CD$ of the Pratt truss. State if the members are in tension or compression. Take that $P_1$ Part B

Determine the force in members $KJ,$ and state if the member is in tension or compression.

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.

$F_{KJ}=$

Part C

Determine the force in members $KD,$ and state if the member is in tension or compression.

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.

Part A

Determine the force in members $CD,$ and state if the member is in tension or compression.

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.
