Consider the following statements: 1. The degree of freedom for lower...
Kinematic Pairs and Degrees of Freedom

A kinematic pair refers to the connection between two or more bodies that allows them to move relative to each other. The degrees of freedom (DOF) of a kinematic pair refer to the number of independent motions that are possible between the bodies.

1. Degree of freedom for lower kinematic pairs is always equal to one

This statement is correct. Lower kinematic pairs refer to those connections between two bodies that allow for pure sliding or rolling motion. Examples include a prismatic joint or a cylindrical joint. These types of joints provide only one degree of freedom, which is the ability to move in a single direction.

2. A ball-and-socket joint has 3 degrees of freedom and is a higher kinematic pair

This statement is incorrect. A ball-and-socket joint provides three rotational DOF but no translational DOF. It is a type of spherical joint and is considered a lower kinematic pair.

3. Oldhams coupling mechanism has two prismatic pairs and two revolute pairs

This statement is correct. The Oldhams coupling mechanism is used to transfer motion between two parallel and offset shafts. It consists of two prismatic pairs that allow for sliding motion and two revolute pairs that allow for rotational motion. Therefore, it provides two DOF.

Conclusion:

Considering the above statements, option A is the correct answer. The degree of freedom for lower kinematic pairs is always equal to one, a ball-and-socket joint is a lower kinematic pair with three rotational DOF, and the Oldhams coupling mechanism has two prismatic pairs and two revolute pairs, providing two DOF.

DOF of lower is not always equal to one ( spherical pair (lower pair) has 3 DOF
. ball and socket is a lower pair. so optio n A is correct
