The force applied on a unit area to produce any change in the volume or length of a body is called:
Correct answer: B. Stress
- A. Strain
- B. Stress
- C. Elasticity
- D. Equilibrium
Explanation
In physics, stress is defined as the force applied per unit area to a material. It is the external force that acts on a body to deform it or cause changes in its volume or length. Stress is an important concept in the study of mechanics and materials science. Therefore, option b) stress is the correct choice.

About Simple Harmonic Motion
Simple harmonic motion is oscillation in which acceleration is directly proportional to displacement and directed toward the equilibrium position. Work includes displacement, velocity, acceleration, phase, period, frequency, amplitude and energy, with applications to springs and simple pendulums. The restoring force and the conditions for SHM distinguish it from general periodic motion.

An airplane is flying in a straight line at a constant altitude. If a wind gust strikes and raises the nose of the airplane, the nose will bob up and down until the plane eventually returns to its original position. These oscillations are:
For a simple harmonic motion the acceleration of the body is _ to displacement and always directed towards _.
In SHM the kinetic energy of the body is maximum when:
A student is performing a lab experiment on simple harmonic motion. He has two different springs (with force constants k1 and k2) and two different blocks (of masses m1 and m2). If k1 =2k2, and m1 = 2m2, which of the following combinations would give the student the spring-block simple harmonic oscillator with the shortest period?
A body of mass 4 kg attached to a spring is displaced through 0.04 m from its equilibrium position and then released. If the spring constant is 400 N/m, find the time period of the vibration?
