Mcq on Cotter joint

The Mechanical engineering, is playing a crucial role in today's Technology.

It Assist you to done things with ease, and also it brings the helpful technologies to modernize our society.

In the field of mechanical engineering,Today we are dealing with the most important objective questions (mcq) on a topic of a MCQ ON COTTER JOINTS - Machine Design.

Let's Brief learn about Cotter joints:-

What is cotter joint?

Cotter joint is a joint used to temporarily joining of two coaxial rod. 
Cotter is a flat wedged with the shape of rectangular cross sectional area and width  is tapered.
The taper is varying from 1 in 48 to 1 in 24.

A Cotter joint is temporary fastening and used to connect rigidly two co-axial rods or bars which are subjected to axial tensile or compressive forces.

Due to centrifugal force cotter joint should not be used for joining of rotating shafts.

It is usually  used in connecting a piston rod to the cross head of reciprocating steam engine.

The cotter joint having following parts:

Spigot, socket, cotter pin, sleeve, Gib etc.

Types of cotter joints:

These following three types are commonly used to connect two rods by cotter.
1. Socket and spigot cotter joint.
2. Gib and cotter joint.
3. Sleeve and cotter joint.

Application of cotter joints:-

  • The cotter joint is used to connect piston rod with the crosshead in steam engine.
  • Used bicycle to connect the pedal and sprocket wheels

  • It is also used in air pump for joining tail rod with the Piston rod.
