Why Multiply by 10 in Dead Load Calculations?

AI Thread Summary

In dead load calculations, multiplying by 10 accounts for the gravitational acceleration (g), which is commonly approximated as 10 m/s². The formula involves calculating the weight of the material by multiplying its density (1000 kg/m³) by its volume (0.6 x 0.020 x 1.0 m³). This results in a force in Newtons per cubic meter, hence the final multiplication by 10 to convert the volume into a weight measurement. The calculation yields a dead load of 120 N/m. Understanding the units and the role of gravitational acceleration clarifies the necessity of this multiplication.

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.

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...

Thread 'Explain this asphalt sheen'

This problem is two parts. The first is to determine what effects are being provided by each of the elements - 1) the window panes; 2) the asphalt surface. My answer to that is The second part of the problem is exactly why you get this affect. And one more spoiler:
