The uniform bar AB weighing 240 lb. is mounted as shown in Figure upon a carriage weighing 480 lb. The center of gravity of the carriage is at C midway between the wheels. If P = 180 lb. and there is no frictional resistance at the wheels, find R1 and R2, and also the horizontal and vertical components of the pin pressure at A.
Consider a floor crane operated by a driver which carries a drum as shown in figure. The total weight of floor crane and driver is 2700 kg acting at the point of center of gravity, G. mm; = 1 = Considering L1 = 14m, L2= 3 m L3 - 6 m, 14 = 2 m LS = 1 m; L6=7m 1. If the weight of the drum lifted by the floor crane is 800 kg, determine the total normal reaction on the rear wheels at A and total normal reaction on the front wheels at B when the boom is inclined at an angle of 25" with the horizontal, 2. Utilizing the same data given above for the same position of boom, determine the largest weight of the drum that can be lifted without causing the crane to overturn. (Hint: When the floor crane tends to overturn about point B, the wheel at A will leave the ground). Note: 1. Consider the entire system as coplanar 2. Take g 9.81 m/s wherever necessary = 9 Total normal reaction on the rear wheels at A= Total normal reaction on the front wheels at B= Largest weight of the drum=
