A 100‐ft steel tape standardized at 68° F and supported under a tension of 20 lb, was found to be 100.012ft long. The tape had a cross‐sectional area of 0.0078 in^2 and a weight of 0.0266lb/ft. The ground is on a smooth level grade, thus the tape will be fully supported. Assume a temperature increase of 19°F. Assume thermal coefficient equal to 0.00000645/°F Determine total correction (due to incorrect length and temperature) to be applied to lay out a horizontal distance of 175 ft.
Problem 3 3 Nine diameter steel (Est = 30,000ksi) reinforcing bars were used when the short 4 concrete (Ec 4500ksi) pier was constructed. After a load P of 150 kip was applied to the pier, the temperature increased 100°F. The coefficients of the thermal expansion for steel and concrete are 6.6 × 10-6/ °F and 6.0× 10-6/ °F, respectively. Determine: (1) The normal stresses in the concrete and in the steel bars after the temperature increases (2) The change in length of the pier resulting from the combine effects of the temperature change and the load. (3) Can we change steel bar to aluminum bar (12.5 × 10-6/ °F) to reduce the cost of reinforcement? Use one sentence to explain your thoughts, no need to calculateⒸ = 10 in. 0.0 10 in.

Solve for what is being required. Room dimensions are: LxWxH = 8.50 m, 5.0 m, 3m. Originally, the room had linoleum flooring with an absorption coefficient of 0.03. Two opposite walls were cladded with unglazed bricks with an absorption coefficient of 0.02, the one having the entrance gypsum door (2.1 m X 0.80 m) with 0.05 abs.co.; the other two were just bare concrete with sliding glass window openings of 1.80m x 1.20 m each; the bare concrete with an abs.co. Of 0.31 and the window glass with 0.18, the ceiling, too , had bare concrete as its finish at 500 Hz. The client would like to renovate the space into an acoustical studio room and would like to change the ceiling and the flooring. The ceiling will have a vinyl faced fiberglass panel with an abs.co. of 0.71, and the floor will have mineral fiber tiles with an abs.co. Of 0.66, all at 500 Hz.
9. A computer room located on the second floor of a five-storey office building is 10m X 7m. The exterior wall is 3.5m high and 10m long; it is a metal curtain wall (steel-backed with 10mm of insulating board), 75mm of glass fiber insulation, and 16mm of gypsum board The single-glazed window (U=5.9 W/m2-K) make-up 30% of the exterior wall. Three computer sets at 500 Watts each and 500 Watts of total lighting power in the room operate 24 hours per day. The indoor temperature is 20°C. Determine the following: a. The heat load, in Kilowatts, if the outdoor conditions is 32°C DB and 23°C WB. b. What would be the load, in Kilowatts, if the windows were double-glazed (U=3.5 W/m2•K)?

A steel tube with 5 cm ID, 7.6 cm OD and k=15W/m °C is covered with an insulative covering of thickness 2 cm and k 0.2 W/m °C. A hot gas at 330° C with h = 400 W/m2oC flows inside the tube. The outer surface of the insulation is exposed to cooler air at 30°C with h = 60 W/m2oC. Calculate the heat loss from the tube to the air for 10 m of the tube and the temperature drops resulting from the thermal resistances of the hot gas flow, the steel tube, the insulation layer and the outside air.
