Question

Dynamics of machine deals with.
1. The relative motion between the parts neglecting the consideration of forces
2. The forces acting on the parts of the machines
3. The apparatus for applying mechanical power
4. The number of inter-related parts, each having a definite motion

Answer 1

Correct Answer - Option 2 : The forces acting on the parts of the machines

Explanation:

Dynamics of machine

• It is a branch of the theory of machines that studies the motion of machines, taking into account the forces acting on them.
• The Dynamics of machine deals with the problems of, the definition of the laws of the motion of the components of mechanisms, control of the motion of the components, determination of frictional losses, determination in the reaction of kinematic pairs, and balancing of machines and mechanisms.
• Analyses the forces and couples on the members of the machine due to external forces (static force analysis) also analyses the forces and couples due to accelerations of machine members (Dynamic force analysis).

Kinematics of machine

• Study of motion of the components and basic geometry of the mechanism and is not concerned with the forces which cause or affect motion. The study includes the determination of velocity and acceleration of the machine members
