1.If the average length of a vehicle is 15 ft and the average space between consecutive vehicles waiting to be served is 3 ft, what is the minimum length for the off-ramp to provide storage for all exiting vehicles 80 percent of the time?
2.Collars A and B are connected by a 25 in long wire and can slide freely on frictionless rods. If a 60 lb force Q is applied to B determine a) tension in wire when (black) x = 9 in and b) corresponding mag of force P required to maintain equilibrium of system
3.Determine initial velocity if a ball from rest is kicked at an initial angle of 58.3 deg, and travels in the x direction 6m and 3m in y direction. take gravity into account.
4.A fireman is standing on a hoist and sprays water at a fire. the fire is 35 ft in the x direction and 20ft downward in the y direction. the water flows at 65 ft/s. determine two possible angles theta at which this can be done. assume the angle below the horizontal is positive.
A new development is to be constructed in Mexico City. Due to the large subsidence, the elevation at the proposed site must be raised prior to construction. The total volume of soil needed to raise the site is 100,000 cubic yards.

A zone in the CBD is projected to contain 1,525,000 ft2 of residential space; 3,675,000 ft2 of service establishments; and atotal retail activity floor area of 2,100,000 ft2.
Ball A is thrown vertically upward from the top of a 20-{\rm m}-high-building with an initial velocity of 3m/s . At the same instant another ball B is thrown upward from the ground with an initial velocity of 16m/s .
An ethanol plant distills alcohol from corn. The distiller processes 2.0 t/h of feed containing 15% alcohol and 82% water; the rest is inert material. The bottoms (waste) produced is 85% of feed and contains 94% water, 3.5% alcohol, and 2.5% inert..
The incremental cash flow between alternatives Z1 and Z2 (Z2 has the higher initial cost). Use an AW-based rate of return equation to determine the incremental rate of return and which alternative should be selected
A brass cube (E=100 GPa, v = 0.25(Poisson's ratio)) is 100 mm long per side. A compressive force of 100kN is applied to one side, while a tension force of 200 kN is applied to a second side.
