3) A torsion spring is used in a hand-held spring clamp. Thejaws of the clamp are 1.5 inches from the pivot. The spring angleis 45° when the clamp is closed and 0° when the clamp is open.Determine torsional spring constant, clamping force when closed andclamping force when open. Use units of torque/rev for torsionalspring constant. Include leg length in Na calculations.
