1.) Consider a metal single crystal oriented such that the normal to the slip plane and the slip direction are at angles of 35.5 and 25.4, respectively, with the tensile axis. If the critical resolved shear stress is 25 MPa, will an applied stress of 30 MPa cause the single crystal to yield? If not, what stress will be necessary? a) Yes it is enough to yield b) No it is not enough to yield, 31 Mpa will be enough c) No it is not enough to yield, 32 Mpa will be enough d) No it is not enough to yield, 33 Mpa will be enough e) No it is too much to yield, 24 Mpa or smaller should it be
