4-in square steel bar subjected to transverse biaxial tensile stressesConsider a 4-in square steel bar subjected to transverse biaxial tensile stresses of 20 ksi in the x direction and 10 ksi in the y direction. (a) Assuming the bar to be in a state of plane stress, determine the strain in the z direction and the elongations of the plate in the x and y directions. (b) Assuming the bar to be in a state of plane strain, determine the stress in the z direction and the elongations of the bar in the x and y directions. Let E= 30103 ksi and  = 0.25.
determine (a) the compression ratio, (b) the cycle efficiency, (c) exhaust temperature, and (d) mean effective pressure (kPa). Draw (e) a P-v diagram and (f) a T-s diagram
A 15cm cube of mass 3kg is lubricated with SAE 10 oil at 20oC (dynamic viscosity of 0.104Ns/m2) slides down a 10o inclined plane at a constant velocity. Estimate the speed of the body if the oil film has a thickness of 2mm and the velocity distrib..
