A firm is considering moving its manufacturing plant from Chicago to a new location. The industrial engineering department was asked to identify the various alternatives together with the costs to relocate the plant, and the benefits. The engineers examined six likely sites, together with the do-nothing alternative of keeping the plant at its present location. Their findings are summarized as follows:
Plant Location First Cost ($000s) Uniform Annual Benefit ($000s)
Denver $300 $52
Dallas 550 137
San Antonio 450 117
Los Angeles 750 167
Cleveland 150 18
Atlanta 200 49
Chicago 0 0
The annual benefits are expected to be constant over the 8-year analysis period.
(a) Construct a choice table for interest rates from 0% to 100%.
(b)IT the firm uses 10% annual interest in its economic analysis, where should the manufacturing plant be located?
the block is fitted between the fixed supports. if the glued joint can resist a maximum shear stress of T(allow)=2ksi, determine the temperature rise that will cause the joint to fail. Take E= 10(10^3)ksi, v=0.2
A ladder of mass 20 lbs. is leaned at an angle of 62 degrees against a smooth frictionless wall. What is the magnitude of the reaction (in lb-wt) where the ladder touches the wall?
Find the discharge with an 80% risk of being equaled or exceeded at least once in the next 10 years. (Hint: first find the annual probability of exceedance for this discharge.)
Write the mass balance equation for an ideal 1D plug-flow stream under steady state conditions with a first-order decaying substance. Solve for the concentration as a function of the concentration x=0, the rate constant kd, longitudinal distance x..

The spillway for a dam is 20 m wide and is designed to carry 125 m3/s at flood stage. A 1:15 ratio model is constructed to study the flow characteristics through the spillway. The effects of surface tension and viscosity can be neglected.
a whirlpool is modeled as the combination of a free and a forced vortex. the maximum velocity in the whirlpool is 10 m/s, and the radius at the juncture of the free and the forced vortex is 10m.
For a cement paste with an initial water-cement ratio of 0.5, by mass, calculate the mass and volumetric composition of 1 cm^3 of HCP under both wet and sealed curing conditions.
A glass is cleaned in 45 0C hot water and placed onthe table bottom up. The room air at 20 0C thatwas trapped in the glass gets heated up to 40 0C andsome of it leaks out so the net resulting pressure inside is 2 kPaabove ambient pressure of 101 kPa...
