Astepper motor with 50 step angles is coupled to a leadscrew through a gear reduction of 4: 1 (four rotations of the motor for each rotation of the leadscrew). the leadscrew has one thread/cm. the worktable driven by the leadscrew must move a distance = 50.0 cm at a feed rate = 80 cm/min. determine (a) the number of pulses required to move the table, (b) required motor speed, and (c) pulse rate to achieve the desired table speed.
