Circle either True or False for the statements below.
True or False If two interlocking gears have the same radius, then the absolute value of the
torque in each gear will be the same.
True or False You can increase power by increasing the angular velocity of the shaft.
True or False You can increase power by slowing down the frequency of the shaft.
True or False Interlocking gears of different radii must experience the same angle of twist.
