A 3x8 member in a diaphragm resists a tension force caused by the lateral wind pressure. Lumber is Select Structural DF-L. A single line of 7/8-in. diameter bolts is used to make the connection of the member to the diaphragm. Cm=1.0, Ct=1.0, and Ci=1.0. Find: a. The maximum axial tension load using ASD. b. The factored axial tension capacity using LRFD.

Different types of steels contain different elements that alter the characteristics of the steel. for each of the following elements, explain what the element does when alloyed with steel.

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?
