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
Explanation / Answer
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.
