An ideal gas, Cp= (5/2)R and Cv= (3/2)R is changed from P(initial)= 1bar and V(initial)= 12m^3 to P(final)= 12bar and V(final)= 1m^3 by the following mechanically reversible processes: (a) Isothermal compression. (b) Adiabatic compression followed by cooling at constant pressure. (c) Adiabatic compression followed by cooling at constant volume. (d) Heating at constant volume followed by cooling at constant pressure. (e) Cooling at constant pressure followed by heating at constant volume. Calculate Q, W, change in U, and change in H for each of these processes, and sketch the paths of all processes on a single PV diagram.
Calculate the tensile modulus of elasticity for a 10 laminated composite consisting of 62 percent by volume of unidirectional carbon fibers and an epoxy matrix under isostress conditions.

If an additional 11-ft lane is added (each direction) and all other factors stay the same, what will be the new level of service?
A runs slope a distance of 156.777 m from one point to another point at a rate of +1.5%. What is the corresponding horizontal distance between the points?
Calculate the force (in Kn) a punch press must exert if it is to punch out a large washer from a strip of 5-mm thick sheet steel with an ultimate shear strength of 400 MPa.
Water flows through a horizotal 45 deg reducing bend with a 36 inch. diameter upstream and a 24 inch diameter downstream, at the rate of 20 cfs under a pressure of 15 psi at the upstream end of the bend. Neglecting head loss in the bend, calculate..
Design a single angle strut connected to a gusset plate to carry 180k n factored load. The length of the strut between center to center intersection is 3m.
The central angle is 35 degrees, the superelevation is 0.08, and 20.6 ft is cleared (for sight distance) from the inside edge of the innermost lane. Determine a maximum safe speed (assuming current design standards) to the nearest 5 mi/h.
