Cotter Joint

A cotter joint is a type of mechanical joint used for rigidly fastening two rods or members together. It consists of a cotter and a cotter pin, which are used to connect the members and prevent them from separating.

Statement 1: Cotter is a flat wedge-like piece inserted through the members at right angles to their axes.

This statement is valid. A cotter is a flat wedge-like piece that is inserted through the members at right angles to their axes. It is usually made of a material such as steel.

Statement 2: Used for rigid fastening of two rods.

This statement is valid. A cotter joint is specifically designed for the rigid fastening of two rods or members. It provides a secure and stable connection between the two rods, preventing any relative motion between them.

Statement 3: Rods to be connected are subjected to tensile or compressive stresses along their axes.

This statement is valid. The rods or members connected by a cotter joint are typically subjected to tensile or compressive stresses along their axes. The cotter joint is designed to withstand these stresses and provide a strong and reliable connection.

Statement 4: Not suitable for joining members under rotation.

This statement is valid. A cotter joint is not suitable for joining members that are under rotation. It is primarily used for connecting members that are subjected to tensile or compressive stresses. If the members are under rotation, a different type of joint, such as a keyway or spline joint, would be more appropriate.

Conclusion

In conclusion, all four statements are valid pertaining to a cotter joint. A cotter is a flat wedge-like piece that is inserted through the members at right angles to their axes. It is used for rigidly fastening two rods or members together and is suitable for connecting rods under tensile or compressive stresses. However, it is not suitable for joining members under rotation.
