Chapter 4, Problem 50P

Solve it correctly please. I will rate accordingly.

Handle forces F1 and F2 are applied to the electric drill. Replace this force system by an equivalent resultant force and couple moment acting at point O. Express the results in Cartesian vector from. Determine the resultant force and the moment of the resultant forse about the point O. Express your answer in terms of the unit vectors i, j and k.

The turnbuckle is tightened until the tension in cable AB is 1.1 kN. Calculate the magnitude of the moment about point O of the force acting on point A. 1.4 m 2.3 m 1.3 m 0.9 m Answer: M= kN-m

Find the moment caused by the force F = 826 N about point A if a = 21 mm and b = 31 mm. 5 b B 12 A D.

1. Determine the magnitude of the moment of the 200-N force about the x axis. Solve 0.3 m F= 200 N the problem using both a scalar and a 45 vector analysis. 120 60 0.25 m 2. The chain AB exerts a force of 20 lb on the 3 ft door at B. Determine the magnitude of the 2 ft moment of this force along the hinged axis x of the door. F= 20 lb B. 4 ft 3 ft 20°

A force F of magnitude 80 N is applied to the gear. Determine the moment (positive if counterclockwise, negative if clockwise) of F about point O. Assume r = 130 mm, 0 = 17° Answer: Mo = Mi N-m

The small crane is mounted along the side of a pickup bed and facilitates the handling of heavy loads. When the boom elevation angle is q = 40°, the force in the hydraulic cylinder BC is 7 kN, and this force applied at point C is in the direction from B to C (the cylinder is in compression). Determine the moment of this 7 kN force about pivot point O assuming counterclockwise is positive. Express your answer in units of N-m. A 110 mm 785 mm C - 0 B 340 mm 360 mm

Replace the two forces acting on the rectangular solid by a wrench. Write the force R and moment Mas vectors and specify the coordinates of the point Pin the x-y plane through which the line of action of the wrench passes. 240 mm 450 mm 160 N 160 N 360 mm Answers: R= (i it j+ i k) N M-( it j+ i k) N-m Coordinates of point P. (ху) - ( )mm

Determine the moment of each of the three forces about point A. Express your answers in newton-meters to three significant figures and separated by commas. Enter a positive value if the moment is counterclockwise and negative value if the moment is clockwise.
