A thin steel disk of an oil separator of 100mm outside diameter is shrunk onto a solid steel shaft
of 20mm diameter. The system is to be designed to make sure the disc does not become loose
at speeds lower than 100000rev/min. Determine the shrinkage allowance required in order to
avoid separation disc and shaft, at a speed of 100000rev/min.
For the material assume a Young's Modulus, Poisson Ratio and density of 210GPa, 0.3 and
7850kg/m³ respectively.
Lenora Manufacturing company is planning to market enamel cups. After conducting
extensive market surveys, the research department provides the following estimates:
a monthly demand of 200 cups at a price of $16 per cup and a monthly demand of 300 cups at
a price of $14 per cup. The financial department estimates that monthly fixed costs will be
$1,400 and variable costs (cost per unit) will be $4.
(a) Assume that the relationship between price p and demand x is linear. Use the research
department's estimates to determine the Lenora's price-demand function, p(x).
(b) What would be the price per cup for an order of 260 units?
(c) Find the revenue function, R(x).
(d) Find the maximum revenue that the company can realize, stating the number of books that
must be sold to obtain this highest revenue.
(e) Assume that the cost function is linear. Use the financial department's estimates to find the
cost function,C(x).
(f) Find the profit function, P(x).
(g) Determine, algebraically, the…
QUESTION 1
(a)
Powder Metallurgy (PM) has become competitive with processes such as casting,
forging and machining, particularly for complex parts made of high strength and hard
alloys. Compare the design considerations for products made of powder metallurgy,
casting and forging process. Evaluate your observation.
(b)
Products made of sheet metals can be easily found around us. Identify some of the
products in your automobile which are made from sheet metal, and discuss the process
or combination of processes required to produce such products.
