Aflexible pavement is known to have a structural number of 4. the pavement is on a soil with a resilient modulus of 5000 lb/in2. the pavement was designed with 90% reliability, an overall standard deviation of 0.4, and a δpsi of 2.0 (a tsi of 2.5). how many 18-kip single-axle loads can be carried per day before the pavement reaches its tsi, if the design life is 20 years?

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

Ajournal bearing has a journal diameter of 3.250 in with a unilateral tolerance of 20.003 in. the bushing bore has a diameter of 3.256 in and a unilateral tolerance of 0.004 in. the bushing is 2.8 in long and supports a 700-lbf load. the journal speed is 900 rev/min. find the minimum oil film thickness and the maximum film pressure for both sae 20 and sae 20w-30 lubricants, for the tightest assembly if the operating film temperature is 160°f. a computer code is appropriate for solving this problem.
