The rolling mill rolls steel sheets with a size of 6, 15 meters. The weight of each sheet is 355.5 kg. what is the thickness of the sheet?
Given:
a = 6 meters – the length of the steel sheet;
b = 15 meters – the width of the steel sheet;
m = 355.5 kilograms is the mass of the steel sheet;
ro = 7800 kg / m3 (kilogram per cubic meter) – steel density.
It is required to determine c (meter) – the thickness of the steel sheet.
Find the volume of the steel sheet:
V = m / ro = 355.5 / 7800 = 0.046 m3 (the result has been rounded to one thousandth).
Find the area of the steel sheet:
s = a * b = 6 * 15 = 90 m2.
Then the thickness of the steel sheet will be:
c = V / s = 0.046 / 90 = 0.0005 meters = 0.5 millimeters.
Answer: The thickness of the steel sheet is 0.5 millimeters.
