Question

the knowledge of electricity is applied in designing a bridge such that it does not bend too much or break under the load of traffic the force of wind and under its own weight .explain using formula.​

Answer 1

Answer:

The knowledge of elasticity is applied in designing a bridge such that it does not bend too much or break under the load of traffic, the force of wind and under its own weight. Consider a rectangular bar length l, breadth b and thickness d supported at both ends, as shown in figure. When a load W is suspended at its middle, the bar gests depressed by an amount given by

δ=Wl34Ybd3
