19. 20. A force F₁ with magnitude 150 N and angle x = 30 deg is applied 2 meters to the right of the rotation axis of a 6 meter long rod aligned along the +x axis. A second force F₂ = (212N, ß = 50 deg) is applied at the center of the rod. Simultaneously, a third force, F3 with magnitude 250 N is applied to the right end of the rod at an angle y = 35 deg (as shown in the figure). Calculate the net torque on the rod. F1 x = 0m 1.0 m of 2.0 m 3.0 m F2 so 6.0 m In the previous problem, assume that the rod has a total mass of 42 kg. Calculate the angular acceleration of the rod resulting from the net torque. (a positive "+" acceleration is counterclockwise.) F3
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.
