Your company is considering the purchase of new earth moving equipment. The total purchase is $240,000 and we pay with $100,000 cash and borrow the rest. (12% per year nominal, compounded monthly for 5 years). The machines last for 7 years and will be worth $35,000 at the end of 7 years. The machines will save approximately $20 per ton of dirt moved. Operating costs for the equipment are $500 per month. At the end of year 3, you will have to do an overhaul and that costs $30,000. Assume that MARR is 1.5% per month and ignore the effect of taxes and depreciation.
a. Compute the monthly payment for the loan. Please be clear and specify the interest rate and the number of periods that you will use in the formulas.
A surface water sample has been evaporated until dry in a crucible dish. The dry (tare) weight of the crucible is 44.642gm. The weight of the residue plus the cruciible is 44.6484gm.
For the FE pin-pin cable model, solve for the deflection and reactions using the partitioned form. What is partitioned form
A beam is 11.5m long. There are two lifting points at 2.2m from each end of the beam. Beam self weight = 4kNm superimposed live load = 12kNm. How to determine what the bending moments are at the lifting points
A proposed square footing carrying a total load of 900 kips is to be constructed on a uniform thick deposit of cohesionless soil. The soil's unit weight is 135 pcf, and its angle of internal friction is 38 degrees.
Determine the horizontal and vertical components of reaction at the supports. Neglect the thickness of the beam
Calculations with steam mixed with additional steam at a different pressure, A steam press at 650Kpa + dryness fraction of 0.9% flows along a pipe at a rate of 3.5Kg per second
(a) Find the Reynolds number for the motion of this baseball through air. (b) Determine the drag force on the baseball under these conditions in N.
Peg P is driven by the fork link OA along the curved path described by r = (2*theta) ft. At the instant theta = pi / 4, the angular velocity and angular acceleration of the link are (theta-1dot) = 3.0 rad/sec and (theta-2dot) = 1.1 rad/sec^2
Estimate the diameter of the tower, based on bottom operating conditions. Assume that the density and viscosity of the bottom liquid are the same as tose for pure water. Make other appropriate assumptions as needed.
An 18 in. newriveted steel pipe 1000 ft long runs from elevation 150 ft toelevation 200 ft. If the pressure at elevation 150 ft is 100 psiand at elevation 200 ft is 72 psi, what flowrate can be expectedthrough the line? (use e = 0.003 ft)
A water line to a home is usually 3⁄4" copper tube. What is the flow rate that can be delivered and still maintain laminar flow in the tube?
