Two blocks of rubber with a modulus of rigidity g 5 12 mpa are bonded to rigid supports and to a plate ab. knowing that c 5 100 mm and p 5 45 kn, determine the smallest allowable dimensions a and b of the blocks if the shearing stress in the rubber is not to exceed 1.4 mpa and the deflection of the plate is to be at least 5 mm.

Amass of 1.5 kg of air at 120 kpa and 24°c is contained in a gas-tight, frictionless piston-cylinder device. the air is now compressed to a final pressure of 720 kpa. during the process, heat is transferred from the air such that the temperature inside the cylinder remains constant. calculate the boundary work input during this process.

Acompressor receives the shaft work to decrease the pressure of the fluid. a)- true b)- false

Assuming compressible flow of air and that the measurements are done at flagstaff a pitot static tube that gives the difference of total and static pressure measures 0.35 m of mercury. what is the velocity of air? assume the temperature to be 300k. (submit your excel or matlab calculation sheet)
