A circular shaft subjected to torsion experiences a shear stress \(\tau\). If the radius of the shaft doubles, the shear stress will
In a 2D stress system on an element, if the normal stresses on the x and y axes are \(\sigma_x\) and \(\sigma_y\), and the shear stress is \(\tau\) (\(\tau_{xy}\)), the normal stress on a plane inclined at 45\(^\circ\) to these axes is:
