A worktable is connected to a leadscrew of pitch 5mm. A stepper motor which drives the leadscrew, receives 10 000 pulses from the control system. A gear couples the motor to the leadscrew and causes the leadscrew to turn at 5 revolutions/second when the motor speed is 600 rev/min. Determine (b) the pulse frequency in Hz, if the step angle is 1.2 degrees
