Concrete can be pre-stressed in structural applications using steel wires stretched in tension prior to the curing of the concrete and upon curing, the tension can be released, compressing the concrete. If steel wires comprising 40% of the composite volume are pulled with 500kN of force and then released once the concrete has cured. What is the amount of force transferred to the concrete?

500kN

Explanation: the total force transfered to the concrete is 500kN force with which it was prestressed.

explanation:

earth's surface is mainly heated by the absorption of infrared radiation from the sun.

evaporation occurs because molecules in liquid water are warmed ( usually by the sun) and vibrate quicker, becoming less dense and rise.

condensation occurs because molecules in water vapor are cooled and therefore vibrate more slowly thus becoming more dense and eventually fall to earth.

lines of equal barometric pressure on a weather map are called: isobars : lines of equal temp on a weather map are called: isotherms.​
