Machine Elements 1: Introduction and Mechanical Systems

A machine element is an individual part of a machine that moves and impacts other parts to make the machine work. An example of a machine element is a gear.

Gears are rotating parts with interlocking teeth that turn against other gears, causing them to turn and transmit rotational force, or torque.

Bearings are used to carry force and reduce friction. An example is the ball bearing, which allows for reduced friction as it rolls freely beneath a moving part.

<p>Shafts and couplings transmit torque and are used to connect parts, especially in vehicles such as cars and motorcycles.</p> Signup and view all the answers
