Determine the moment of the 225-Ib force about point A and about point O.

Determine the required magnitude of force F if the resultant couple moment on the frame is 350 Ib.ft clockwise 2 ft-2 ft- B 30° 2 ft 150 lb 150 lb 2 ft 30 2 ft

5. Determine the moment about point B for each of the individual three forces acting on the beam, and indicate their directions. F1 = 400 lb F2 = 450 lb %3D B. 0.5 ft 8 ft 7 ft 6 ft 30° F3 = 150 lb

1. Aforce F is applied to the wrench. Determine the moment of this force about point 0. Solve the problem using both a scalar analysis and a vector analysis.

if F= 300 lb, determine the resultant couple moment

1) Replace the force at A by an equivalent resultant force and couple moment at point P. Express the results in Cartesian vector form. 4 ft 10 ft F = 120 lb 8 ft 6 ft- 8 ft-
