increases

decreases

remains same

none of the above

Answer is:

decreases

ultimate stress to working stress

working stress to ultimate stress

breaking stress to ultimate stress

ultimate stress to breaking stress

Answer is:

Explanation:

The ratio of ultimate stress to the working stress is known as factor of safety. Its value is more than one.

the axis of load

an oblique plane

at right angles to the axis of specimen

would not occur

Answer is:

stresses varying between two limits of equal value, but of opposite sign

stresses varying between two limits of unequal value, but of opposite sign

stresses varying between two limits of unequal value but of same sign

all of the above

Answer is:
