A numerical control (NC) machine tool table is powered by a servomotor, leadscrew, and optical encoder. The leadscrew 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 leadscrew). The optical encoder is connected directly to the leadscrew and generates 200 pulses/ rev of the leadscrew. 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.

Three children are standing on a 5×5-m raft. The weights of the children at Points A, B, and C are 375 N, 260 N, and 400 N, respectively. If a fourth child of weight 425 N climbs onto the raft, determine where she should stand if the other children r..
Determine the displacement and stress fields in the spherical body. Using the stress field obtained, determine the stresses at the surface of a rigid inclusion in an infinite elastic medium.
What are the strategic options for legacy system evolution? When would you normally replace all or part of a system rather than continue maintenance of the software?
two staged steam turbines are arranged as shown in the diagram with a reheater in between the two stages. steam enters
