An existing six-lane divided multilane highway with a field-measured free-flow speed of 45 mi/h serves a peak-hour volume of 4,000 veh/h. with 12% trucks and no rvs. the phf is 0.88. the highway has rolling terrain. what is the likely level of service for this section?

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

Aplate clutch has a single pair of mating friction surfaces 250-mm od by 175-mm id. the mean value of the coefficient of friction is 0.30, and the actuating force is 4 kn. a) find the maximum pressure and the torque capacity using the uniform-wear model. b) find the maximum pressure and the torque capacity using the uniform-pressure model.

The higher the astm grain-size number, the coarser the grain is. a)-true b)-false
