The cart and its contents have a total mass of 4500 kg and a center of gravity at G as shown in Figure Q4. The coefficient of static friction between the wheels and the tracks is l = 0.4 when the wheels are locked. The normal forces acting on the wheels at (A and B) are independent as to whether the wheels are locked or not. Therefore, 10kN 0.9 m 0.15 m : 0.6 m 土 1.5 m Figure Q4: The cart.

Calculate the horizontal force P on the light 15° wedge necessary to initiate movement of the 59-kg cylinder. The coefficient of static friction for both pairs of contacting surfaces is 0.39. Also determine the friction force Fg at point B. (Caution: Check carefully your assumption of where slipping occurs.) Answers: P= i 596 FB=366 59 kg B N N
The strut AB of negligible mass is hinged to the horizontal surface at A and to the uniform 24-kg wheel at B. Determine the minimum couple Mapplied to the wheel which will cause it to slip if the coefficient of static friction between the wheel and the surface is 0.40.

Determine the maximum downward force Pmax that can be applied to wedge A that will keep the assembly in equilibrium. Based on the value of the force in link BC, determine whether block C will slip or tip first. At Pmax, what are the frictional forces between wedge A and block B, fAB, and between wedge A and wall D, SAD? The weight of block C is 192 N while that of the wedge is negligible. Draw the FBDs of wedge A, block B, and block C. Label correctly all the forces (especially normal and frictional forces with proper subscripts) and indicate the direction of the impending motion next to each FBD. Note that the weight of block B, though not negligible, is not necessary in the computation. W HAD 0.27 D P A B 60° HAB= 0.14 |sg =0 E C 1 m HCF = 0.375 F R 2.4 m 3.2 m
