Sam applies a constant force of 170 N towards the left to a mechanical system (Mas spring damper). He records that the mass moves 1.9 m to the left before returning to the right. Sam is sitting at his desk located 18.5 m to the left of the Mass trying to get a good measurement of the mass's travel. Sam dials in a force to apply and the mass just touches his desk (18.5 m from the resting location of the mass). No impact is felt by the desk. What force did Sam dial in to apply to the mass to the left?
Simple harmonic motion
Simple harmonic motion is a type of periodic motion in which an object undergoes oscillatory motion. The restoring force exerted by the object exhibiting SHM is proportional to the displacement from the equilibrium position. The force is directed towards the mean position. We see many examples of SHM around us, common ones are the motion of a pendulum, spring and vibration of strings in musical instruments, and so on.
Simple Pendulum
A simple pendulum comprises a heavy mass (called bob) attached to one end of the weightless and flexible string.
Oscillation
In Physics, oscillation means a repetitive motion that happens in a variation with respect to time. There is usually a central value, where the object would be at rest. Additionally, there are two or more positions between which the repetitive motion takes place. In mathematics, oscillations can also be described as vibrations. The most common examples of oscillation that is seen in daily lives include the alternating current (AC) or the motion of a moving pendulum.
