The system shown is supported by a pin at A and a roller at E. It is composed of three straight members AC, BE, CD as well as the pulley at C that holds the freely hanging weight. All member connections are pins. Member AC is _____.

L = 465 lb and the support reactions are Ay = 651 lb acting up, Hy = 744 lb acting up and Hx = 0. Noting that the force in member GH = 744 lb (compression), is FI is a zero-force member?

L = 465 lb and the support reactions are Ay = 651 lb acting up, Hy = 744 lb acting up and Hx = 0. Noting that the force in member GH = 744 lb (compression), determine if member GI is in tension or compression.

If the crate weighs 200 lb and μs = 0.4 between its base and the inclined surface, determine the smallest force P that will prevent the crate from sliding down the plane.

When calculating the moment created about point A due to the force at B, which is the correct calculation process to use?

The main focus of IR is to solve the ‘______ problem’

Determine the magnitude of the component of the force vector FD = [3 i + 6 j – 2 k] kN that lies parallel to the line connecting the two points A(1, -5, 9) m and B(11, 8, -2) m.

Assuming the crate does not tip, it weighs 846 lbs, and μs = 0.4 between its base and the floor, determine the friction force developed along the base if P = 237 lb.

L = 465 lb and the support reactions are Ay = 651 lb acting up, Hy = 744 lb acting up and Hx = 0. Noting that the force in member GH = 744 lb (compression), is DK is a zero-force member?

The system shown is supported by a pin at A and a roller at E. It is composed of three straight members AC, BE, CD as well as the pulley at C that holds the freely hanging weight. If the vertical reaction at point E is 32 kN (upward), determine the compressive force developed in member CD.
