Chapter 4, Problem 71P

Current Attempt in Progress The 4.0-lb force is applied at point A of the crank assembly. Determine the moment of this force about point O. F = 4.0 lb 22 0.60" -y 2.10". Answer: Mo =( i i+ i j+ i k) Ib-in.

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.

Determine the moment of the 115-lb force about point A and about point O.

Problems: 2/31 The 4-kN force F is applied at point A. Compute the moment of F about point O, expressing it both as a scalar and as a vector quantity. Determine the coordinates of the points on the x- and y-axes about which the moment of F is zero. y, m A (1.2, 1.5) 3. F=4 kN <, m 2/32 The rectangular plate is made up of 1-ft squares as shown, A 30-lb force is applied at point A in the di- rection shown. Calculate the moment Mg of the force about point Bby at least two different methods. 30 lb 1 ft 1 ft

The pipe assembly is subjected to three forces of F1 = {3.00, 4.00, -2.00} kip, F2 = {0, 0,-4.00} kip, and F3 = {-3.00, 0, 0} kip. Determine the sum of the moment of the forces 1) about x-axis (the unit vector of x is i) and 2) about line AC. Express the result as a Cartesian vector.

Replace the loading acting on the frame by an equivalent resultant force and couple moment acting at point A. 80 lb 60 lb 3 ft 3 ft- 3 ft 3 ft B A 2 ft + 4 ft 75 lb 40 lb

4. Determine the resulting moment about point O from the forces shown. Assume the length of each side of the cube is 4m.
