A $$DC$$ servomotor is directly driving an $$NC$$ table. The pitch of the lead screw of the table is $$5$$ $$mm.$$ The motor rotates at $$100$$ $$rpm$$ for an applied voltage of $$10V.$$ If the voltage speed characteristic of the motor is linear, the applied voltage for a table of $$3m/min$$ is equal to:

The component development and manufacturing activities when assisted by a computer are: Computer Aided Graphics $$(CAG), CAD, CAM, CAPP$$ and Computer Aided Quality Control $$(CAQC).$$ The most appropriate sequence of these activities is

$$A\,\,2{1 \over 2}\,\,$$ control in a typical $$CNC$$ machine provides
