What is the correct statement regarding the stress over the section of a shaft in torsion?

a) a normal stress that varies linearly over the section
b) a normal stress that is uniform over the section.
c) a shear stress that is uniform over the section.
d) a shear stress that varies linearly over the section

d) A shear stress that varies linearly over the section.

Explanation:

Given that shaft is under pure torsion

As we know that relationship between shear stress in the shaft and radius given as

For solid shaft

Therefore shear stress given as

T=Applied torque on the shaft

τ=Shear stress at any radius r

From the above equation we can say that shear stress is vaying linearly with the radius of the shaft

Therefore the answer will be d.

how is this a question? in order for me to answer it i have to understand the question

explanation:

answer:

yes that is right have a good day
