Answer:
Option D
Material has uniform properties throughout.
Explanation:
A homogeneous material is a material that exhibits uniform properties throughout and these properties cannot be separated. These materials can be metals, ceramics or alloys that exhibit similar properties throughout. The similar properties may include evaporation point, density and other properties.
Answer:
During film condensation on a vertical plate, heat flux at the top will be higher since the thickness of the film at the top, and thus its thermal resistance, is lower.

Explanation:
beam span = 25 ft
dead load = 0.6 kip/ft
live load = 2.1 kip/ft
factored load = 1.2*0.6 +1.6*2.1=4.08 kip/ft
moment in beam = 4.08*252/8=318.75 kip-ft = 3825 kip-in
design strength =0.9* 50 = 45 ksi
plastic section modulus required = 3825/45=85 in3
Moment in beam in ASD = (0.6+2.1)*252/8 = 210.9 kip-ft
lighest W section from LRFD = W21x44
lightest W section from ASD = W21x44
