At 24°c, a rod is exactly 20.37 cm long on a steel ruler. both the rod and the ruler are placed in an oven at 280°c, where the rod now measures 20.53 cm on the same ruler. what is the coefficient of thermal expansion for the material of which the rod is made? the linear expansion coefficient of steel is 11 x 10-6 1/c°.

Explanation:

= Original length of rod

= Coefficient of linear expansion =

Initial temperature = 24°C

Final temperature = 280°C

Change in length of a Steel is given by

Change in material rod length will be

The coefficient of thermal expansion is given by

The coefficient of thermal expansion for the material is

answer

procedural programming, object-oriented programming

explanation

procedural programming is a type of computer programming language that specifies a series of well structured steps and procedures   within its development period of time. it contains a systematic order of statements, functions and commands to complete a computational task or program. it is centered on creating procedures. while object oriented programming is a programming language that is centered on creating objects rather that actions and data rather than logic.. it has four principles which are inheritance, polymorphism, abstraction and encapsulation
