AI Thread Summary
The discussion centers on solving a fifth-order polynomial equation for the variable 'D' in hydraulics. It suggests that graphical or numerical methods are the most effective approaches for finding a solution. Participants recommend rewriting the equation in the form f(D) = 0 to simplify the problem. Additionally, it is advised to replace other variables with defined constants to reduce complexity. Overall, the focus is on practical strategies for tackling complex polynomial equations.

Looks like you've got a fifth order polynomial on your hands. Probably best to solve via graphical or numerical methods.

Why not start by wrestling it into polynomial form f(D) = 0? Don't be afraid to replace the clutter of other variables (which will have constant values for a given D) with new constants that you can define accordingly.
 
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...
