A cotter is a flat wedge shaped piece of rectangular cross-section and its width is tapered (either on one side or both sides) from one end to another for an easy adjustment. The taper varies from 1 in 48 to 1 in 24 and it may be increased up to 1 in 8, if a locking device is provided. The locking device may be a taper pin or a set screw used on the lower end of the cotter. The cotter is usually made of mild steel or wrought iron. A cotter joint is a temporary fastening and is used to connect rigidly two co-axial rods or bars which are subjected to axial tensile or compressive forces.

Assertion (A): A cotter joint is used to rigidly connect two coaxial rods carrying tensile load.
Reason (R): Taper in the cotter is provided to facilitate its removal when it fails due to shear.
Explanation:
A cotter joint is a type of mechanical joint that is used to connect two coaxial rods or tubes. It is commonly used in applications where a rigid connection is required between two rods carrying tensile load. The cotter joint consists of a socket or a hole in one rod and a corresponding slot or groove in the other rod. The joint is secured by a cotter pin or wedge-shaped piece of metal that fits into the slot and socket.
The assertion (A) is true because a cotter joint is indeed used to rigidly connect two coaxial rods carrying tensile load. The joint provides a secure and rigid connection between the rods, allowing them to transmit tensile forces without slipping or moving relative to each other.
The reason (R) is also true because the taper in the cotter is provided to facilitate its removal when it fails due to shear. When a shear load is applied to the cotter joint, it may fail and become damaged. In such cases, it is necessary to remove and replace the cotter pin. The taper in the cotter makes it easier to remove by allowing it to be wedged out of the slot or socket. The taper provides a gradual increase in thickness, allowing the cotter pin to be easily pushed out without getting stuck.
Therefore, both the assertion (A) and reason (R) are true, and the reason (R) is the correct explanation of the assertion (A). The taper in the cotter is specifically designed to facilitate its removal when it fails due to shear, ensuring easy maintenance and replacement of the cotter joint.
Reason (R): Taper in the cotter is provided to facilitate its removal when it fails due to shear.
