The critical resolved shear stress of a BCC metal is 7 MPa. A single crystal of this alloy is the [0 0 1] direction. What slip system is activated? Make a sketch of the BCC crystal structure Draw the stress in the appropriate direction Draw the densest plane and direction that will be activated by the stress Calculate the yield stress that will cause plastic deformation.
Important information about Pressure Cooker, Steam is leaving a pressure cooker whose operating pressure is 30 psi. It is observed that the amount of liquid in the cooker has decreased by 0.4 gal in 45 minutes after the steady operating conditions..
Determine the smallest horizontal force required to lift the 260- crate. The coefficient of static friction at all contacting surfaces is = 0.7. Neglect the mass of the wedge.
What is the inner tube surface temperature at the outlet, where fully developed conditions may be assumed?
