hanging at the end of a 2.0-m-long light string that is
connected to a pivot point. (a) Calculate the magnitude of the
torque (due to the force of gravity) about this pivot point when
the string makes a 8.0° angle with the vertical. (b) Does the
torque increase or decrease as the angle increase? increase or
