Ashaft made of stainless steel has an outside diameter of 42 mm and a wall thickness of 4 mm. determine the maximum torque t that may be applied to the shaft if the allowable shear stress is equal to 100 mpa.

Explanation:

Using equation of pure torsion

where

T is the applied Torque

is polar moment of inertia of the shaft

t is the shear stress at a distance r from the center

r is distance from center

For a shaft with

Outer Diameter

Inner Diameter

Applying values in the above equation we get

x

Thus from the equation of torsion we get

Applying values we get

T =829.97Nm

answer:

i lost in getting someone back.

i learned that people are really two-faced and no matter how angelic someone appears they always have a devil side and that you cant trust anyone anymore no matter how dear they are to you.

if your wondering who it waz it waz mah still miss her tho
