What is the force in member AC of the following statically indeterminate truss to the nearest 0.001k if P = 18.1k? D A .P C₁ 6 ft B

2. Determine the force in each member of the truss connected at D when F = 800 N acting in the y-direction. The 3D truss is supported by ball-and-sockets at A, B, and E. Hint: Position-unit vector approach is your friend. FAD = FBD = FCD = 5m 2 m 1m 1.5 m. B 2m C & E

Problem 1) The space truss below has a force F = {−200î + 400ĵ + OÊ}N acting at joint D. Find all the support reactions and forces in all members. For each member, state whether it is in tension or compression. D F 1 m 5 m 2 m - 1.5 m N B 2 m E

Determine the force in each member of the space truss and state if the members are in tension (T) or compression (C). The truss is supported by ball-and-socket joints at A, B, and E. Set F = {-200i+ 400j} N. Hint: The support reaction at E acts along member EC. Why? 5 m -2 m- 1 m- 1.5 m. B D 2 m F E
