A large company in the communication and publishing industry has quantified the relationship between the price of one of itsproducts and the demand for this product as Price = 150- 0.01 x Demand for an annual printing of this particular product. The fixed costs per year (i.e., per printing) =$50,000 and the variable cost per unit =$40. What is the maximum profit that can be achieved if the maximum expected demand is 6,000 units per year? What is the unit price at this oint of optimal demand?
The shaft diameter is 100 mm. Calculate the largest principal stresses and maximum shear stress that will occur in the shaft.
Is this flow laminar. What is the viscosity of the oil. For the same flow in the opposite directio, what manometer reading can be expected.
Could all the people in china hold back the water behind the three gorges dam?
If given a brittle material with a known tensile strength, Sut, and a known compressive strength, Suc, use the four main fracture criteria (MNSC, BCM, MM, and MIIM) to determine the shear stress, tau, in terms of the material properties Sut and Su..
A rectangular channel 5 m wide carries a discharge of 10 m^3/s at a uniform depth of 3 m. The channel is running on a slope of 0.0025 m/m. Estimate wall shear stress and friction velocity. Assume the density of flowing water as 1000 kg/m^3.
determine the adequacy of W16x40(A-36) of steel beam that supports a uniform load of 800 pounds per foot over a span of 30 feet
A soil deposit has a void ratio of 0.89, is the void ratio is reduced to 0.59 by compaction; find the percentage volume less due to compaction.
Suppose the summer daily demand for water use in Phoenix is normally distributed with a mean of 310 million gallons/day and a standard deviation of 45 million gallons/day. Also suppose the city has reservoirs whose combined storage is 350 million ..
A moves downward a distance of 3.6 ft, and mass B moves a distance x. What is the value of x 2. Find the speed of mass B for a given speed of mass A The system is released from rest and mass A moves downward at a constant speed of 8.0 ft/s.
Water enters the pump of a steam power plant as saturated liquid at 20 kPa at a rate of 45 kg/s and exits at 6 MPa. Neglecting the changes in kinetic and potential energies and assuming the process to be reversible
A horizontal curve is designed for a two-lane road in a mountainous terrain. The following data are known: Deflection angle: 40 degrees Tangent: 436.76 Station of PC: 2695 + 73.89 Side friction factor = 0.12 Superelevation = 8% Superelevation run-off..
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.
