Why do they put flexible connections in the road on a bridge? Put it into five complete sentences

1 answer:

7 0

Flexible connections are used because bridges sway. If there were steel or non flexible connections, the road would crumble. Another reason is steel would expand or contract in the heat or cold. If the steel expanded or contracted, then the road would be weak. And since the people on the road don't want it to crumble, the architect put flexible connections instead of hard ones.

muminat

Answer:

Explanation:

Assuming that Liquid X is considered to possess a greater viscosity as well as higher surface tension than liquid Y. Then, liquid X will tend to harbour more pressure inside the liquid.

In addition to that, the greater the surface tension, the greater the force required to expand the liquid's surface area.

This in turn makes the force required to make the loop 5% wider to be greater in FX rather than FY.

Thus, option a is the correct answer.
