4. A single crystal is subjected to a uniaxial tensile stress of 100 MPa along [100] direction. Critical resolved shear stress of the slip plane in the figure is given as 38 MPa. For the following orientations given in the table, calculate resolved shear stress (Trs) and say whether slip occurs or not on that plane. . deg. 1, deg. Trss.
