(2) Brake mean effective pressure (psia)

(3) Torque at 1000RPM (lbf-ft)

(4) Indicated horsepower

(5) Friction hosepower

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?

Draw the engineering stress-strain curve for (a) bcc; (b) fcc metals and mark important points.
