You have 2 tensile specimens of different materials but which are otherwise identical. at a load of 100n, which will show the lower strain: (a).the sample with a young's modulus of 17 gpa (b). the sample with a young's modulus of 1000 kpa (c). neither, they will have the same strain. (d). there is not enough information to determine an answer

At steady state, air at 200 kpa, 325 k, and mass flow rate of 0.5 kg/s enters an insulated duct having differing inlet and exit cross-sectional areas. the inlet cross-sectional area is 6 cm2. at the duct exit, the pressure of the air is 100 kpa and the velocity is 250 m/s. neglecting potential energy effects and modeling air as an 1.008 kj/kg k, determine ideal gas with constant cp = (a) the velocity of the air at the inlet, in m/s. (b) the temperature of the air at the exit, in k. (c) the exit cross-sectional area, in cm2
