Question

a bar of uniform cross section is subjected to axial stress of 100 mpa. consider an oblique plane making an angle 'theta' with the direction of axial stress. calculate the normal stress and shear stress on this oblique plane, if (i) theta

Answer 1

The normal stress on the oblique plane is the same as the original axial stress of 100 MPa, but the shear stress cannot be calculated without more information.

Step-by-step explanation:

To calculate the normal stress and shear stress on an oblique plane subjected to an axial stress, we can use the equations for shear deformation. The normal stress, also known as the axial stress, is the same as the original axial stress applied to the bar, which is 100 MPa. The shear stress on the oblique plane can be calculated using the formula:

Shear stress = Shear modulus * Shear strain

Since we don't have the exact value for the shear modulus or the shear strain, we can't calculate the shear stress without more information.
