Consider a 25 m metal rod at 20°C. It is dangling from edge of a building and is 3 cm from ground. Now the rod is heated to 100 °C. Will it touch the ground? (coefficient of linear expansion, a = 1.1 x 10 SK)
Question 7 (1 point) A metal rod 40.0000-cm long at 33 °C is heated to 60 °C. The length of the rod is then measured to be 40.125 cm. The coefficient of linear expansion of the metal is °C-1. (Round your answer to six decimal places) Your Answer: Answer
a) If an iron rod 1.5 m long at 20 degree C and expands by 1.416 mm when heated to 100 degree C. Find the coefficient of linear expansion for iron. b) A large wooden barrel needs an iron band to be placed around the rim of its base. The iron band is made slightly smaller than the diameter of the barrel's base so that it may be heated placed over the barrel and shrunk tightly into place. If the...
