The shaft is always stepped with ________ diameter at the middle portion and __________ diameter at the shaft ends.
Explanation: Maximum diameter is in the middle portion while it is minimum at the ends.
______ is used for a shaft that supports rotating elements like wheels, drums or rope sleaves.
Explanation: That is axle and not a spindle.
Axle is frequently used in torque transmission.
Explanation: Axle is a shaft supporting rotating elements.
Counter shaft is a secondary shaft.
Explanation: It is a secondary shaft used to counter the direction of main shaft.
Hot rolling produces a stronger shaft then cold rolling.
Explanation: Cold rolling produces stronger shaft as grain structure isn’t deformed in cold working.
Is it necessary for an axle to be ______ with respect to rotating element?
Explanation: The axle may be stationary or rotate with the element.
Shafts are subjected to ______ forces.
Explanation: Shafts are subjected to tensile forces.
When the shaft is subjected to pure bending moment, the bending stress is given by?
Explanation: Stress =My/I where y=d/2 and I=πd⁴/64.
Which of the following act on shafts?
Explanation: Shaft is subjected to torsional moment as well as bending moment.
When the shaft is subjected to pure torsional moment, the torsional stress is given by?
Explanation: Stress=Mr/J where r=d/2 and J=πd⁴/64.
