A single crystal of a BCC metal is oriented so that the direction is parallel to the applied stress. The critical resolved shear stress required for slip is 80.98 . Calculate the magnitude of the applied stress required to cause slip to begin in the direction on the slip plane. (Express your answer to three significant figures. If no shear stress is resolved, enter UNDEF.)

Asolid cylinder is concentric with a straight pipe. the cylinder is 0.5 m long and has an outside diameter of 8 cm. the pipe has an inside diameter of 8.5 cm. the annulus between the cylinder ad the pipe contains stationary oil. the oil has a specific gravity of 0.92 and a kinematic viscosity of 5.57 x 10-4 m2/s. most nearly, what is the force needed to move the cylinder along the pipe at a constant velocity of 1 m/s?
