The use of a single-acting die assembly in a ‘deep drawing’ process is one method commonly used to make drinks cans. with the aid of diagrams, explain the role of the punch, the die, the blank, and the blank holder in this process.

Consider a large isothermal enclosure that is maintained at a uniform temperature of 2000 k. calculate the emissive power of the radiation that emerges from a small aperture on the enclosure surface. what is the wavelength ? , below which 10% of the emission is concentrated? what is the wavelength ? 2 above which 10% of the emission is concentrated? determine the wavelength at which maximum spectral emissive power occurs. what is the irradiation incident on a small object placed inside the enclosure?
