a) Speed lever
b) Feed Lever
c) Tumbler gear lever
d) Friction clutch
View Answer
Explanation: Tumbler gear lever is used to reverse the direction of lead screw relative to the direction of spindle movement in lathe machine.
4. Which of the following arrangement is used in the movement of carriage along the ways?
a) Rack and pinion
b) Spindle mechanism
c) Crank and slotted lever mechanism
d) None of the mentioned
View Answer
Explanation: Rack and pinion mechanism is used in movement of carriage by flywheel. Rack is gear of finite diameter.
5. Which of the following have a live centre?
a) Tail stock
b) Headstock
c) Tool post
d) None of the mentioned
View Answer
Explanation: Head stock has live centre and it is called live because spindle rotates here and is not at rest during machining.

a) Cross slide
b) Saddle
c) Compound rest
d) None of the mentioned
View Answer
Explanation: Cross slide move in a direction normal to the axis of spindle during the process of machining in lathe machine.
9. Which of the following is used to give power feed during cutting of threads?
a) Rack and pinion
b) Planer mechanism
c) Quick return mechanism
d) Using spilt nut
View Answer
Explanation: Split nut are used to engage lead screw to give power feed in lathe during the process of machining in lathe machine.
