Mechanical Engineering : Strength Of Materials QUESTIONS AND ANSWERS :: part1 : 1 to 5

Following Mechanical Engineering Multiple choice objective type questions and answers will help you in BSNL JTO, GATE 2014 and IES 2014 examinations :

1.The intensity of stress which causes unit strain is called

unit stress
bulk modulus
modulus of rigidity
modulus of elasticity
principal stress.

2.The Young's modulus of a wire is defined as the stress which will increase the length of wire compared to its original length

half
same amount
double
one-fourth
four times.

3.Percentage reduction of area in performing tensile test on cast iron may be of the order of

50%
25%
0%
15%
60%.

4.If the radius of wire stretched by a load is doubled, then its Young's modulus will be

doubled
halved
become four times
become one-fourth
remain unaffected.

5.During a tensile test on a specimen of 1 cm cross-section, maximum load observed was 8 tonnes and area of cross-section at neck was 0.5 cm2. Ultimate tensile strength of specimen is

4 tonnes/cm2
8 tonnes/cm2
16 tonnes/cm2
22 tonnes/cm2
none of the above.
