How much longer (ΔL) is a 594.94 m steel bridge at the end of the day when its temperature has increased by 24.5 oC? Assume the coefficient of thermal expansion of steel is 1.20 x 10-5 oC-1.

Older railroad tracks in the U.S. are made of Part A 12-m-long pieces of steel. When the tracks are laid, gaps are left between the sections to prevent buckling when the steel thermally expands. If a track is laid at 16° C, how large should the gaps be if the track is not to buckle when the temperature is as high as 50° C? The coefficient of linear expansion of soft steel is 1.1 × 10-5 °C-1.

A cramming student warms 0.500 L of cold coffee in a Pyrex carafe. Full carafe of coffee at 20°F. How much coffee has spilled when the coffee and carafe reach 95°C? Given that the carafe is an isotropic solid, Pyrex has a linear thermal expansion coefficient of 3.3 x 10-6 K-1 and water (coffee) has 207 x 106 K-1.

What is the change in length of a 3.4-cm-long column of mercury if its temperature changes from 35 ºC to 35.3 ºC, assuming the mercury is unconstrained? The thermal coefficient of expansion of mercury is 6×10-5 /oC.

A hollow aluminum cylinder 19.5 om deep has an internal capacity of 2.000 L at 21.0°C. It is completely filled with turpentine at 21.0°C. The turpentine and the aluminum cylinder are the slowly warmed together to 79.0°C. (The average linear expansion coefficient for aluminum is 24 x 10-c, and the average volume expansion coefficient for turpentine is 9.0 103) (a) How much turpentine overflows? cm³ (b) What is the volume of turpentine remaining in the cylinder at 79 0°C? (Give your answer to at least four significant figures) (c) If the combination with this amount of turpentine is then cooled back to 21.0°C, how far below the cylinder's rim does the turpentine's surface recede? om

Thank u! A steel rule is calibrated for measuring lengths at 20.00°C. The rule is used to measure the length of a Vycor glass brick: when both are at 20.00°C, the brick is found to be 30.90 cm long. If the rule and the brick are both at 85.00°C, what would be the length of the brick as measured by the rule? Coefficient of linear expansion a for steel is 12.0 x10^-6 K-1 and for glass (Vycor) is 0.750 x 10^-6 K^-1.

Brass 0.030 m 5.0 µm Brass has linear thermal expansion coefficient a = 19 × 10-6rC . The picture shows a design defect in an electrical assembly: if the screw expands enough to touch the surface on the left, a dangerous short circuit will occur. The picture shows the assembly at 15°C. What is the maximum tempe ure the assembly can tolerate? 46.9°C 32.6°C 23.7°C 27.4°C 19.3°C
