...that BC is the radius of the axle. Then the proportion teaches us that the power and weight will be in **equilibrium when the power is to the weight as the radius of the axle is to the radius of the wheel.** The Compound Wheel and Axle When more than one wheel and axle are connected, so that the axle of each... | |
