A steel tyre of 1.2 m inner diameter at 20^@C is to be fitted on a cartwheel of 120.33 cm diameter of the tyre. Calculate the temperature to which the steel tyre is to be raised so that it will just slip on the wheel. (alpha_(Steel) = 11 xx 10^-6//^@C)

The diameter of a metal ring is D and the coefficient of linear expansion is alpha . If the temperature of the ring is increased by 1^(0)C , the circumference and the area of the ring will increases by

Solve the following problrms using two variables: The fore wheel of a tractor makes 120 revolutions more than the rear wheel in going 720 m. If the diameter of the fore wheel is doubled and the diameter of the rear wheel is increased by 1 1/2 times the present diameter, then the fore wheel makes 20 revolution more than the rear wheel in going the same distance . Find the circumference of each wheel.
