An air compressor does 2.5 × 106 joules of work in raising the pressure of a quantity of air while the temperature of the air remains constant. what is the heat added to the system? identify the thermodynamic process.

Determine the change in width a, height b, thickness t when a plate is subjected to the uniform distributed load and is made of material having modulus of elasticity e=230 gpa and poisson's ratio ν=1/3. given : a=400 mm and b= 300 mm also the uniformly distributed load in downward y direction of plate is 2 mn/m and in the positive x direction is 3 mn/m and t=20 mm
