1.)What is the difference between couple and angular momentum and how they are related ?
Ans: Couple is product of moment of inertia and angular acceleration. Angular momentum is the product of moment of inertia and angular speed. Time rate of change of angular momentum of body is equal to external couple acting on the body.
2.)Give example of rigid link and flexible link ?
Ans: Connecting rod and belt respectively.
3.). How many degrees of freedom are there in a constrained mechanism ?
Ans: One.
4.). What are Herringbone gears and what for these are used ?
Ans: Herringbone gears are double helical gears and used to eliminate axial thrust.
