The torsional assembly consists of a cold-rolled stainless steel tube connected to a solid cold-rolled brass segment at flange
C
. The assembly is securely fastened to rigid supports at
A
and
D
. Stainless steel tube (1) and (2) has an outside diameter of 4 in., a wall thickness of
0.14in
., and a shear modulus of
G=11700ksi
. The solid brass segment (3) has a diameter of 2.375 in. and a shear modulus of
G=4500ksi
. A concentrated torque of
T_(B)=5.3kip
-ft is applied to the stainless steel pipe at
B
. Assume
L_(1)=55in.,L_(2)=26in
., and
L_(3)=
25 in. Determine: (a) the maximum shear stress magnitude
\tau _(st )
in the stainless steel tube. (b) the maximum shear stress magnitude
\tau _(br)
in brass segment (3). (c) the rotation angle
\phi _(C)
of flange
