The 0.5-mm gap exists at 27°C.arrow_forwarda. Let the tensile stress in a tension test be σ and the shear stress in a torsion test be τ. Draw a stress Mohr circle for each test (let the specimen axis, i.e. longitudinal direction, be x-axis and the transverse direction be y-axis) and express both the maximum principal stress (σmax) and the maximum shear stress (τmax) in terms of σ (for tension test) or τ (for torsion test). Mark the x-axis on the Mohr’s circle. Also indicate the directions of σmax and τmax with respect the x-axis for each case.

- Determine the resulting maximum value of the normal stress. Specify the orientation of the plane on which these maximum values occur. **The answer is tensile stress is 0 ksi at 90 degrees. **The answer is compressive stress is 7 ksi at 0 degrees. Can you explain how that is? This was my thought process: I know that tensile would be zero because the force P is actually going inwards and not outwards. I know that means that there would be a compressive force. I am confused on the angles, how is a tensile force going 90 degress if there technically is no force in the tensile direction. And how is there a compressive force at 90 degrees if there is a stress? thank you!arrow_forwardI need the answer quicklyarrow_forwardA test piece is cut from a brass bar and subjected to a tensile test.
