Answer:
the maximum shear stress in the bar = 9.55 MPa
the twisting angle =
Explanation:
From the diagram below;
Torque (T) = 2 kN × 5 mm + 2 kN × 5 mm
=
= 200 N.m
Now; If we divide the shaft into two parts AC & BC
Then :
------------ equation (1)
At the junction :
⇒
replace into above equation (1)
Again:
Now ; we can deduce that the maximum shear comes from since
So;
where;
R = 20 mm
D = 40 mm = 0.04 m
Then;
Thus ; the maximum shear stress in the bar = 9.55 MPa
b)
Again:
Thus, the twisting angle =
