Ahollow steel shaft with and outside diameter of (do)-420 mm and an inside diameter of (di) 350 mm is subjected to a torque of 300 knm, as shown. the modulus of rigidity g for the steel is 80 gpa. determine: (a) the maximum shearing stress in the shaft. (b) the shearing stress on a traverse cross section at the inside surface of the shaft (c) the magnitude of the angle of twist for a (l) -2.5 m length.

a.  

b.

c. rad.

Explanation:

Given:

We know that

J for hollow shaft

(a)

 Maximum shear stress

      ⇒K=0.83

(b)

We know that

So

(c)

rad.

the warning light flashes for a second or two when the engine starts. if it stays on, there's must be something wrong with the coolant. you should never dare to continue driving when the light is on. pull over as soon as possible and shut the engine off.

hope this is what you're talking about
