A simple pendulum consits of a 3.0 kg point mass hanging at the end of a 2.0 long light string that is connected to a pivot point.
a. Calculate the magnitude of the torque (due to the force of gravity) around this pivot point when the string makes a 5 degree angle with the vertical.
b. Repeat this calculation for an angle of 15 degrees.

Torque= mgl *sinTheta, where theta is 90+ your angle. Draw a sketch and confirm that. I did it in my head.
