The drive unit for a positioning table is driven by a leadscrew directly coupled to the output shaft of a stepping motor. The pitch of the leadscrew = 0.18 in/rev. The table must have a linear speed = 35 in/min. If the relationship between leadscrew pitch p and number of step angles n, is as follows: n=1250p/rg, determine (a) the minimum number of step angles (pulse/rev) in the stepping motor to achieve the required accuracy, (b) the associated step angle, and (c) the frequency of the pulse train required to drive the table at the desired speed.

A cam-follower system similar to that shown in Figure 3-15 (p. 103) has a mass m = 1kg, a spring constant k = 1 000 N/m, and a damping coefficient d = 19.4 N-s/m. Findthe undamped and damped natural frequencies of this system.
If one node is observed at a frequency of 1000 RPM, during a whiring of a simply supported long slender rotating shaft. The first critical speed of the shaft in RPM is ______?
A NC machine tool table is powered by a servomotor, lead screw, and optical encoder. The lead screw has a pitch = 5.0 mm and is connected to the motor shaft with a gear ratio of 16:1 (16 turns of the motor for each turn of the lead screw). The optical encoder is connected directly to the lead screw and generates 200 pulses/rev of the lead screw. The table must move a distance = 100 mm at a feed rate = 500 mm/min. Determine (a) the pulse count received by the control system to verify that the table has moved exactly 100 mm; and (b) the pulse rate and (c) motor speed that correspond to the feed rate of 500 mm/min. Solve the problem assuming the optical encoder is directly coupled to the motor shaft rather than to the lead screw.
