The copper pipe has an outer diameter of 2.50 in. and an inner diameter of 2.30 in. if it is tightly secured to the wall and three torques are applied to it, determine the shear stress developed at points a and

b. these points lie on the pipe's outer surface. sketch the shear stress on volume elements located at a and b

Shear stress

J=0.053431m 4

wp max=48.7 MPa

Kindly find the attached for part b

Explanation:

d0=2.5in=0.0635

di=2.3in=0.05842m

c0=d0/2=0.032m

ci=di/2=0.029

J=π2 (c0 4 −ci 4 )

J=1.5715(0.032 4 −0.029 4 )

J=1.5715(1.05−0.71)x10 −6

J=0.053431m 4

T max =813.5Nm

wp max =T max c0/J

wp max=813.5X0.032/(0.53431X10 −6)  

wp max=48.7 MPa
