Mechanical Engineering : Strength Of Materials QUESTIONS AND ANSWERS :: part1 : 6 to 10

Following Mechanical Engineering Multiple choice objective type questions and answers will help you in BSNL JTO, GATE 2024 and IES 2024 examinations :

6.True stress-strain curve for materials is plotted between

load/original cross-sectional area and change in length/original length
load/instantaneous cross-sectional area original area and log.
load/instantaneous cross-sectional area and change in length/original length
load/instantaneous area and instantaneous area/original area
none of the above.

7.Which is the false statement about true stress-strain method

It does not exist
It is more sensitive to changes in both metallurgical and mechanical conditions
It gives, a more accurate picture of the ductility
It can be correlated with stress-strain values in other tests like torsion, impact, combined stress tests etc.
It can be used for compression tests as well.

8.It equal and opposite forces applied to a body tend to elongate it, the stress so produced is called

internal resistance
tensile stress
transverse stress
compressive stress
working stress.

9.In a tensile test on mild steel specimen, the breaking stress as compared to ultimate tensile stress is

more
less
same
more/less depending on composition
may have any value.

10.Modulus of rigidity is defined as the ratio of

longitudinal stress and longitudinal strain
volumetric stress and volumetric strain
lateral stress and lateral strain
shear stress and shear strain
linear stress and lateral strain.
