The original Bridge of Lionsdrawbridge in St. Augustine, Florida, was a roller-bascule design. The bascule, or movable leaf, was opened by rolling along its circular base in response to a horizontal force produced by a motor-driven wormscrew mechanism. a) If it is known that the motor shaft experienced a torque of 575 lb. in while rotating at 1100 rpm during a bridge opening, what was the minimum horsepower required for the motor
