A street bridge is 5.5m long if the linear expansion of steel is 0.00001 oc How much will it expand when temperatures is by 10oc? Give answer in Cm

Explanation:

Given that,

Length of a street bridge, l = 5.5 m

The coefficient of bridge,

We need to find how much will it expand when temperatures is by 10°C.

The change in length per unit original length is given by :

Hence, the length will expanded 550.055 cm.
