Cotter Joint Design, Parts, Working and Applications

A cotter joint is a mechanical joint used to connect two coaxial rods and transmit tensile or compressive load from one rod to the other. The connection is made by inserting a flat wedge-shaped piece called a cotter into matching slots provided in the connected members. Unlike a screwed connection, the cotter joint does not … Read more

What is Stress and Strain Curve?

When a solid object (such as an iron rod or a metal plate) is gradually subjected to force, it either stretches or deforms slightly. The amount of this strain or deformation depends on the amount of force applied. The graph that explains this entire behavior is called Stress and Strain Curve. This curve fully reflects … Read more
