Repeat Problem 2.16 where the weight of the gearbox is 40 lb.
Problem 2.16
The drawing (Figure P2.16) shows an exploded view of an 1800-rpm motor, a gear box, and a 6000-rpm blower. The gear box weighs 20 lb, with center of gravity midway between the two mountings. All shafts rotate counterclockwise, viewed from the blower. Neglecting friction losses, determine all loads acting on the gear box when the motor output is 1 hp. Sketch the gear box as a free body in equilibrium.
A freight-car axle AB is loaded approximately as shown in the figure, with the forces P representing the car loads (transmitted to the axle through the axle boxes) and the forces R representing the rail loads (transmitted to the axle through the w..
