Find the equation P = shaft power from T by T is spring scales weight x length x q is saved from the center of the motor until the arm is installed at the end of the spring scale.
Find a shaft from the equation P = T, where T is the weight of the spring balance xqx the distance from the center of the motor until the end of the arm is mounted a spring balance.
Find the equation's shaft P = T by T weight spring balance that records x Q x distance from the center of the motor to the arms at the end was installed spring balance.
