A 32-mm thick AISI 1020 steel plate is sandwiched between two 2024-T3 aluminum plates, one 12-mm thick and the other 20-mm thick, and compressed with a bolt and nut with no washers. The bolt is M10 x 1.5, property class 5.8. a) Determine a suitable length for the bolt, rouded up to the nearest 5 mm b) Estimate the bolt stiffness c) Estimate the stiffness of the members d) Calculate the joint constant C.

The filament of an incandescent lamp has a temperature of 2000k. calculate the fraction of radiation emitted in the visible light band if the filament is approximated as blackbody

The thermal expansion or contraction of a given metal is a function of the f a)-density b)-initial temperature c)- temperature difference d)- linear coefficient of thermal expansion e)- final temperature f)- original length

Asteam is contained in a rigid tank with a volume of 1 m3. initially, the pressure and temperature are 7 bar and 500 oc, respectively. the temperature drops due to cooling process. determine: (1) the temperature at which condensation begins in °c, (2) the fraction of the total mass that has condensed when the pressure decreased to 0.5 bar. (3) the volume in m3 occupied by saturated liquid at the final state?
