An imposed displacement field on a solid of square geometry idealized as plane strain case made of a linear isotropic material with material properties E = 30 × 106 psi and = 0.3 is given by u(x, y) = 1 + 3x + 4x 3 + 6xy 2 v(x, y) = xy − 7x 2 a) Determine the expressions for xx, yy and

What difference(s) did you notice using a pneumatic circuit over hydraulic circuit.explain why the pneumatic piston stumbles when it hits an obstacle.

An ideal otto cycle with air as the working fluid has a compression ratio of 8. the minimum and maximum temperatures in the cycle are 300 k and 1340 k. use constant specific heats at room temperature to determine (a) the amount of heat transferred to the air during the heat- addition kj/kg, (b) the thermal efficiency, and (c) the thermal efficiency of a carnot cycle ope limits. process, in rating between the same temperature
