Question

Two shafts of same length and material are joined in series. if the ratio of their diameters is 2, then the ratio angle of twist will be _____.

a.2

b.4

c.8

d.16

Answer 1

Hey.

Here is the answer.

Angle of twist ,x is directly proportional to 1/J

and, so x is directly proportional to 1/d^4

So, as d2/d1 = 2

so, x1/x2 = (d2/d1)^4 = 2^4 = 16

So, Two shafts of same length and material are joined in series. If the ratio of their diameters is 2, then the ratio angle of twist will be 16.

Thanks.
