From an alloy, two specimens are machined and tested separately under tension and compression. The engineering stress-strain curves as well as the true stress-true strain curves for tension and compression are plotted in the same diagram. Identify the correct statements:
P. The engineering stress-strain curves in tension and compression are identical.
Q. The true stress-true strain curve in compression is lower than the true stresstrue strain curve in tension due to Bauschinger effect.
R. The true stress-true strain curve in tension is above the corresponding engineering stress-strain, curve.
S. The true stress-true strain curve in tension and compression are identical.
Consider the following statements.
1. Surface tension of liquid depends on length but not on the area, like the elastic property.
2. SI unit of surface tension is N/m.
3. Surface tension is a scalar quantity because it has no specific direction for a given liquid.

Which of the following statements is/are true?
Determine the correctness or otherwise of the following Assertion (a) and Reason (r).
Assertion: During rolling, front tension and (or) back tension are (is) employed to decrease rolling load.
Reason: Roll pressure decreases due to lowering of flow stress as a result of front tension/back tension.
A cam should be designed only using uniform rise and fall within half of the cam, the remaining is dwell period, and without any dwell period in between the rise -fall periods and rise and fall periods should be same. The maximum rise in follower is 30 mm. How much the follower will rise when the follower is 120 degrees from its initial position of a cam?
