Two concrete spans that form a bridge of length L are placed end to end so that no room is allowed for expansion (Fig. P16.63a). If a temperature increase of T occurs, what is the height y to which the spans rise when they buckle (Fig. P16.63b)?
One easy way to reduce heating (and cooling) costs is to add extra insulation in the attic of a house. Suppose a single-story cubical house already had 15 cm of fiberglass insulation in the attic and in all the exterior surfaces. If you added an extra 8.0 cm of fiberglass to the attic, by what percentage would the heating cost of the house drop? Take the house to have dimensions 10 m by 15 m by 3.0 m. Ignore air infiltration and heat loss through windows and doors, and assume that the interior is uniformly at one temperature and the exterior is uniformly at another.
For the human body, what is the rate of heat transfer by conduction through the body's tissue with the following conditions: the tissue thickness is 3.00 cm, the difference in temperature is 2.00 , and the skin area is 1.50 m2. How does this compare with the average heat transfer rate to the body resulting from an energy intake of about 2400 kcal per day? (No exercise is included.)
The thermal conductivities of human tissues vary greatly. Fat and skin have conductivities of about 0.20 W/m K and 0.020 W/m K, respectively, while other tissues inside the body have conductivities of about 0.50 W/m K. Assume that between the core region of the body and the skin sin face lies a skin layer of 1.0 mm, fat layer of 0.50 cm, and 3.2 cm of other tissues. (a) Find the R-factor for each of these layers, and the equivalent R-factor for all layers taken together, retaining two digits. (b) Find the rate of energy loss when the core temperature is 37C and the exterior temperature is 0C. Assume that both a protective layer of clothing and an insulating layer of unmoving air a absent, and a body area of 2.0 m2.
A brass bar is joined at one end to a 70 cm copper bar and at the other end with boiling water at 1 atm. In order to achieve conductive heat transfer, the copper-free end is brought into contact with a mixture of water and ice also at 1 atm. Both bars have a cross sectional area of 0.00500 m2. The sides of the rods are insulated, so there is no heat loss to the surroundings. If after 5 minutes 50 g of ice melts, find the length of the brass bar.

A copper bar of thermal conductivity 401 W/(m·K) has one end at 114°C and the other end at 24.0°C. The length of the bar is 0.180 m, and the cross-sectional area is 1.00 × 10−6 m2. If two such bars were placed in parallel (side by side) with the ends in the same temperature baths, what would the rate of heat conduction P be?
A metal rod is 10 cm long and has a diameter of 2 cm one end is in contact with steam at 100 deg C while the other end contacts a block of ice at 0 deg C. The cylindrical surface of the rod is carefully insulated so heat flows only from one end to end. In a time of 20 minutes, 320 grams of ice melts. What is the thermal conductivity of the metal?
