A 4.8-m-tall, 30-cm-diameter concrete column supports a 5.0×105 kg load. By how much is the column compressed?

• Physics -

compression distance = (column length)*strain

Strain = Stress/(Young's modulus)

Look up Young's modulus for concrete and do the numbers. The modulus might be dfferrnt if the concrete is reinforced with steel, as most is.

• Physics -

According to information online, use 26,000*10^6 Pascals for Young's modulus of concrete, whether reinforced or not.
