17 a) A student finds following values from graph between M and x in the static method of determining spring constant k: M1 320gram, M2 = 120gram, x1 8.21cm and x2 = 0.72cm. What is the spring constant? Mass of the hanger is unknown. fMl is changed to 360gram, what is the change in x1? ) A student finds following values to determine spring constant by dynamical method. Number of oscillations N = 30 oad 130gram and average time taken for N oscillation = 12.2 seconds. oad 300gram and average time taken for N oscillation = 18,2 seconds. What is the spring constant? Mass of the hanger is unknown. f oad = 400gram and what is average time taken for N oscillation?
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.
