A two-lane rural highway has a ONE WAY ADT of 4,000 with 25% trucks and 4% annual growth. 50% of the trucks travel on the design lane with a truck factor equal to the one found in Q4. Compute the ESAL’s for a design period of 20 years.

Acubic shaped box has a side length of 1.0 ft and a mass of 10 lbm is sliding on a frictionless horizontal surface towards a 30 upward incline. the horizontal velocity of the box is 20 ft/s. determine how far up the incline the box will travel (report center of mass distance along the inclined surface, not vertical distance)
