Question

An axially loaded bar is subjected to a normal stress of 173 mpa. The shear stress in the bar is

Answer 1

Answer:

Explanation:

Hey,

We can solve this as below:

=> "Here, An axially loaded bar is subjected to a normal stress of 173 mpa.

So, Normal stress=P=173 MPa

=> To calculate the shear stress in the bar we can use following equation:  

=> Shear stress =q=(P/2) sin2θ  

Therefore , q= (173/2) = 86.5  

=> q=(P/2) sin2θ  =86.5*1=86.5 MPa. {sin2*45 = 1}

Thus, The shear stress in the bar is 86.5 MPa"
