The concrete post (Ec 5 3.6 3 106 psi and ac 5 5.5 3 1026 / 8F) is reinforced with six steel bars, each of 7 8-in diameter (Es 5 29 3 106 psi and as 5 6.5 3 1026 / 8F). Determine the normal stresses induced in the steel and in the concrete by a temperature rise of 658F.

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?

Slip occurs via two partial dislocations because of (a) the shorter path of the partial dislocation lines; (b) the lower energy state through partial dislocations; (c) the charge balance.

Inspection for bearing condition will include: (clo4) a)-color b)-smell c)-size d)-none of the above
