Question

Classify the piston of a car engine into translatory, rotatory, and oscillatory motion.

Answer 1

1. Motion of the piston of a car engine is oscillatory motion.
2. When the body moves to and fro (backward and forward) about its mean position, its motion is called oscillatory motion.
3. In oscillatory motion, the entire body moves to and fro.
4. Some examples of oscillatory motion are the motion of a swing, the pendulum of a clock, and the piston of a car engine.
