Chapter 4, Problem 44P

The trap door is held open by the rope AB. If the tension in the rope is T = 60 lb, determine its moment about the y-axis.

Determine the moment of the force F about point A in terms of F and d. Use (a) the scalar method; and (b) the vector method.

The moment of the force F=50i100j70klb about point O is MO=400i+410j300klbft. Determine the coordinates of the point where the line of action of F intersects the xz-plane.

The man pulls on the rope with a force of F = 20 N. Determine the moment of this force about the base of the pole at O. Solve the problem two ways, i.e., by using a position vector from O to A, then O to B. B 1.5 m 3 m F 4 m 10.5 m

2) The uniform slender bar has a mass of 50 kg. If the tension in the cable AB is 400 N, 650 mm determine the moment about point O 30

Determine the moment of the force F about point P. Express the result as a Cartesian vector.

1) Determine the moment of the force about point 0. 100N 2m -5m-

İf the two forces F1={100i-120j+75k} lb and F2={-200i+250j+100k} lb act at A, determine the resultant moment produced by these forces about point O.
