An automobile manufacturer is testing the suspension system of their latest car model. They load the car, which has a mass of 1,110 kg, with four test dummies, each with a mass of 71.9 kg. The car is placed onto a horizontal platform which can oscillate vertically with an adjustable frequency. The engineers find that when the platform's frequency is set to 1.70 Hz, the car's suspension vibrates at its maximum amplitude. The platform oscillation is then turned off. As four test dummies are removed from the car, the car's body will rise by what distance (in cm)? X 14.7 TE +h
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.
