SUMMARY

The discussion centers on the calculation of dead load in structural engineering, specifically the formula for determining the load per unit area. The calculation involves multiplying the density of the material (1000 kg/m³) by the volume (0.6 m x 0.020 m x 1.0 m) and then by 10 to account for gravitational acceleration (g = 10 m/s²). This results in a final dead load of 120 N/m². The multiplication by 10 is essential for converting mass to weight in Newtons.

PREREQUISITES
  • Understanding of basic physics concepts, particularly gravitational force.

density = 1000
volume = 0.6 x 0.020 x 1.0
answer = 0.6 x 0.020 x 1000 x 10 = 120N/m

can someone please explain to me why you have to times it by 10 at the end to get 120n/m

i understand the equation just don't understand the x 10 part at the end.

Try writing down the units as well. You may see the answer easier. And also take into consideration that g is often given as 10m/s^2.
