A 10.0-m long steel cable needs to be able to support a mass of 96 kg without stretching more than 0.50 cm. Determine the necessary diameter of the cable. The elastic modulus of steel is 200 x 109 Pa. [3.5 mm] A hollow aluminum cylinder has a volume of 2.500 L at 30.00°C. It is completely filled with acetone at the same temperature. The combination is slowly warmed to a new temperature of 80.00°C. Some of the acetone overflows, and...

An aluminum wing on a passenger jet is 40m long when it's temperature is 15 degrees C. At what temperature would the wing be 3cm (0.03m) shorter? The coefficient of linear expansion for aluminum being used is (25 * 10^-6). I keep plugging this into an equation for thermal expansion, but I am not getting numbers that look right. [change in L (0.03) = (25 * 10^-6)(40)(change in T, T-15)]

A segment of steel railroad track has a length of 30.000 m when the temperature is 0.0°C. (a) What is its length when the temperature is 40.0°C? SOLUTION Conceptualize Because the rail is relatively long, we expect to obtain a measurable increase in length for a 40°C temperature increase. problem Categorize We will evaluate a length increase using the discussion of this section, so this part of the example is an analysis Use AL aLAT and the value of the...
