The typical energy requirement for runners is 1 kcal/km per kilogram of body weight, and each mole of oxygen intake allows for the release of 120 kcal of energy by oxidizing (burning) glycogen.

You notice during the construction that two concrete spans of the bridge of total length L; = 270 m are placed end to end so that no room is allowed for expansion (figure (a)). In the opening storyline for the thermodynamics chapter, we talked about buckling sidewalks. The same thing will happen with spans on bridges if allowance is not made for expansion (figure (b)). You want to warn the construction crew about this dangerous situation, so you calculate the height y to which the spans will rise when they buckle in response to a temperature increase of AT = 19.0°C. a b T T+AT y = Ider Enter a number. made by one span, with its thermally expanded length as the hypotenuse.arrow_forwardAn open cylinder of air has a radius of 38.0 cm and a height of 50.0 cm, as shown in figure (a). 50.0 cm Ah The air pressure is 1.00 atm and the temperature is 13.5°C.

- Two horizontal wires are joined end to end, each with a diameter of 2.000 mm. The two joined wires are connected to fixed points a total distance of 4.00000 m apart. When both wires are at a temperature of 43.0°C, each wire has an unstretched length of 2.00000 m, and the tension in each is negligible. The first wire is made of steel and extends from x = -2.00000 m to x = 0, and the second is made of brass and extends from x = 0 to x = 2.00000 m. The temperature of both wires is then lowered to 18.0°C, and the wires stay joined together as they cool. The steel wire is composed of an alloy that has an average coefficient of linear expansion of 1.10 x 10-5 (°C) -1 and a Young's modulus of 2.00 x 1011 N/m². The brass wire is composed of an alloy that has an average coefficient of linear expansion of 1.90 x 10-5 (°C)¹ and a Young's modulus of 9.10 x 10 10 N/m².
