AI Thread Summary
To calculate the net force on a flat roof due to wind blowing at 35 m/s, Bernoulli's equation is applied. The dynamic pressure is determined using the formula for dynamic pressure, which is half the product of air density and the square of wind velocity. The pressure difference between the outside air and the air inside the house is then used to find the net force on the roof. The net force can be calculated by multiplying the pressure difference by the roof area of 240 m². This approach effectively utilizes fluid dynamics principles to solve the problem.

Homework Statement



If wind blows at 35 m/s over a house, what is the net force on the roof if its area is 240m^2 and is flat?


Homework Equations




Bernoulli's equation.


The Attempt at a Solution



I have no idea how to belgin =|

I think you can use dynamic pressure = \frac{density * velocity^2}{2}

Then use pressure = force/area.
 
To find the net force on the roof, compare the reduced pressure of the moving outside air to the pressure of the air within the house.
 

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...
