Consider a hot working operation in which there is no work hardening, but the flow stress is sensitive to the strain rate. Calculate the maximum strain rate that can be used in the deformation if the flow stress cannot exceed 210 MPa. The strength constant is 175 MPa, and the strain rate sensitivity exponent is 0.1. Assume that there is no effect of friction with the tooling. (2 points)
