Galaxy Industries is a manufacturing company that produces two toy doll models: the Space Ray and the Zapper. The Space Ray can be sold for a profit of $8/dozen and a profit of $5 can be made if a dozen of Zappers are sold. Each figurine is made of plastic, whose availability for production is limited to 1000lbs each week. Furthermore, a maximum of 40hrs are available for production each week. Space Rays require 3mins of production for each dozen produced and 4mins are required to manufacture a dozen Zappers. The marketing department has also notified you that the total number of figurines should not exceed 700 dozens each week and that the total number of Space Rays should not exceed the total number of Zappers by 350 dozens each week. A summary of the requirements for the project is tabulated below.
Constraints Space Ray Zapper Availability [/week]
Plastic [lbs/dozen] 2 1 1000 lbs
Production time [mins/dozen] 3 4 40 hrs
Profit [$/dozen] 8 5
Using a graphical approach, determine the optimal amount of Space Rays and Zappers that need to be produced in order to maximize profits every week. Describe the type of solution you obtained and clearly state your choice of decision variables, objective function as well as constraints
Determine the force in each member of the truss and state if it is in tension or compression. Set P=400 lb and d=4 ft.
A discharge meter to be used in a 40 cm pipeline carrying oil (kinematic viscosity = 10-5 m2/s, density = 860 kg/m3) is to be calibrated by means of a model (1/4 scale) carrying water (T = 20°C and standard atmospheric pressure).
if D has a mass of 600 kg, determine the required mass of C, the maximum sag h of the cable, and the length of the cable between the pulleys A and B. The Beam has a mass per unit length of 50 kg/m.
A concrete building has floor area 10 m by 20 m and is 4 m high. THe building has four windows with a height 1.6 m and a width 2 m. After 10 minutes gases in the room have an average temperature of 700 degree Celcius.
A horizontal circular plate weighing 60-lb is suspended from three wires that are attached to a support at D and form 30 degree angles with the vertical. Determine the tension in each wire.
An orifice meter was calibrated for dry air at T=90 F and P=1.3 atm. The calibration data are as follow: dp(inches of water): 0,0.5,1.0,2.0,3.0,4.0,5.0 Q(ft^3/minute): 0,2.0,3.0,4.2,5.0,5.5,5.8
The company will use an annual interest rate of 10%. Annual maintenance and pumping costs may be considered to be paid in their entireties at the end of the years in which their costs are incurred.
Estimate the inside diameter, wall thicknes and outside diameter of the pipe. The carbon steel pipe has tensile yield strength of 250 MPa. Assume safety factore of 2 and a corrosion allowance of 2mm. The maximumoperating pressure (MOP) is 55 bar.
