11.3.12 Shafts and Lever Arms. Shafts and lever arms are used extensively in electromechanical drive systems. Transmission shafts are rotating members and transmit power and torque from one location to another while spindles are short shafts and axles are nonrotating shafts. Shafts can be solid or hollow.Web

The lever arm is the handle that the user pulls to operate the crusher. The connecting rod connects the lever arm to the crushing plate. Assuming a simple design, we can estimate the lengths as follows: - Lever arm: The length of the lever arm can vary depending on the design and desired mechanical advantage. Let's assume a length of …Web

It is often necessary to increase or decrease the torque produced by a motor to suit different applications. Recall that the length of a lever can increase or decrease the force on an object at the expense of the distance through which the lever must be pushed. Similarly, the torque produced by a motor can be increased or decreased through the use of gearing.Web

Explanation: The mechanical advantage of a lever of a grain crusher is the ratio of the output force to the input force. It is a measure of how much easier it is to do a job using the lever compared to doing it without. For example, if the output force is twice as great as the input force, then the mechanical advantage of the lever would be 2.Web

Since an impulse is a force acting for some amount of time, it causes an object's motion to change. Recall Equation 9.6: J → = m Δ v →. Because m v → is the momentum of a system, m Δ v → is the change of momentum Δ p →. This gives us the following relation, called the impulse-momentum theorem (or relation).Web
