    (B) The middle of the cutting stroke
    (C) Beginning of the cutting stroke
    (D) None of the above

4. One complete rotation of the bull gear in a shaper gives ram
    (A) One forward stroke
    (B) One return stroke
    (C) One forward and one return stroke
    (D) No movement

5. The feed of shaper takes place
    (A) At the end of return stroke
    (B) At the middle of return stroke
    (C) At the start of cutting stroke
    (D) At the middle of cutting stroke

6. Which one of the following is used to align the shaper vice with the machine table in position?
    (A) Try square
    (B) Dial test indicator
    (C) Straight edge
    (D) Vernier caliper

7. Which one of the following statements is NOT correct?
    (A) For changing the direction of feed, pawl is to be rotated 180°
    (B) When shaping 'T' slot, the function of clapper box is not used
    (C) Pawl mechanism of a shaper is a unit, which regulates the speed of rpm
    (D) When cutting 'T' slots in a shaper, clapper block need not to be lifted

8. In ratchet and pawl mechanism, the rotary movement of the gear or crank slide is converted to linear movement by
    (A) Connecting rod
    (B) Rack and pinion
    (C) Worm and worm wheel
    (D) Shaft and pulley

    (C) Hydraulic mechanism
    (D) Cam mechanism

10. Why it is necessary to maintain an approach distance between the cutting tool and the work while working on shaping machine?
    (A) To cool down the cutting edge of the tool bit
    (B) To avoid any ridge at the end of the workpiece
    (C) To allow the chips to fall and clear the cutting edge
    (D) To enable the clapper box to return to cutting position

    (A) The tool cuts during forward motion while the job is fed
    (B) The tool cuts on both directions while the job is fed
    (C) The job is kept stationary and the feed is given to the tool
    (D) The tool is kept stationary and the feed is given to the job
