The tension in a ligament in the human knee is approximately proportional to the extension of the ligament, if the extension is not too large. A.)If a particular ligament has an effective spring constant of 163 N/mm as it is stretched, what is the tension in this ligament when it is stretched by 0.760 cm? b.)If a particular ligament has an effective spring constant of 163 N/mm as it is stretched, what is the elastic energy stored in the ligament when stretched by 0.760 cm?
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.
