 Calculate the room-temperature forging force for a solid, cylindrical workpiece made of 5052- O aluminum that is 3.5 in. high and 5 in. in diameter and is to be reduced in height by 30%. Let the coefficient of friction be 0.15. Estimate the forging force for the workpiece, assuming that it is a complex forging and that the projected area of the ash is 30% greater than the projected area of the forged workpiece.  To what thickness can a solid cylinder of

When at a point two solid phase changes to one solid phase on cooling then it is known as a) eutectoid point b) eutectic point c) peritectic point d) peritectoid point

If the thermal strain developed in polyimide film during deposition is given as 0.0044. assume room temperature is kept at 17.3 c, and thermal coefficient of expansion for the film and the substrate are 54 x 10^-6c^-1 and 3.3 x 10^-6c^-1respectively. calculate the deposition temperature.

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?
