The frame supports a centrally applied distributed load of 1.8 kip/ft. Determine the state of stress at the critical location. The pins at C and D are at the same location at the neutral axis for the cross-section. If the frame is made of steel with tensile strength 25 ksi and compressive strength of 30 ksi, determine the safety factor.

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?

Burgers vector is generally parallel to the dislocation line. a)-true b)-false

Machinery that is a key part of the process and without which the plant or process cannot function is classifed as: (clo4) a)-critical machinery b)-essential machinery c)-general purpose machinery d)-none of the specified options.
