Designers may employ solid modeling to give their works a more three-dimensional and organic appearance than would be possible by just putting together lines. Explain?
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.
Solid modelling gives designers the ability to mould and mould their creations. Explain?

- 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.
