Given the force-displacement data from two #4 (Diameter = 4/8") rebar tension tests, plot the stress-strain curves for each specimen and determine their material properties. The data files posted on WebCampus contain the raw data, including applied force and extensometer gauge length. You will need to convert the force (load in lb) and length (laser extensometer in inches) into stress and strain. Use Microsoft Excel to manipulate your data and make your plots.

Line joining liquid phase with liquid and solid phase mixture is known as: a) liquidus b) solidus c) tie line d) none of the mentioned

Apiston-cylinder with a volume of 0.25 m3 holds 1 kg of air (r 0.287 k/kgk) at a temperature of 100 c. heat transfer to the cylinder causes an isothermal expansion of the piston until the volume triples. how much heat is added to the piston-cylinder?

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?
