QUESTION 19

At which point along the radius of a wire, the shear stress due to a Torque takes the maximum value?

at half of the radius

at a distance of 2/3 from the center

at the center

at a distance equal to the radius

QUESTION 18

For a torsional member with a varying cross-section, to find the angle of twist you must integrate the equation along the length

True

False

QUESTION 16

Hooke\'s Law states that there is a proportional relationship between shear stress and strain equal to:

=P/A

G=/

E=/

=V/A

a-		at half of the radius
b-		at a distance of 2/3 from the center
c-		at the center
d-		at a distance equal to the radius

19) Option D is correct. the shear stress due to a Torque takes the maximum value at a distance equal to the radius which is at surface of the shaft.

18) True. For a torsional member with a varying cross-section, to find the angle of twist you must integrate the equation along the length.

16) Option C is correct. Hookes law is stating that stress is proportional to strain. E is proportionallity constant.
