AI Thread Summary
The problem involves four individuals pulling on a rope at the corners of a square, with specific forces applied at each corner. The calculations for the net force in the x and y directions are incorrectly using 60-degree angles; the correct angles should be determined based on the square's geometry. The net force can be calculated using the vector components of each individual's force. The discussion highlights the need for clarification on the angles involved and accurate calculations to find the resultant force and its direction. Correcting these calculations will yield the desired net force and angle from the positive x-axis.

Homework Statement


4 people stand at the corners of a square. Fred stands at point (0,0)
Ted at (1,0) Ed at (1,1) and ned at (0,1). they each pull on a rope connected to the center of the square
(0.5,0.5). Fred exerts 11N, Ted exerts 11N, Ed 17N and Ned 15N. what is the net force exerted on the center point and what is the angle from the positive x-axis


Homework Equations





The Attempt at a Solution


Fx = 17cos60+11cos60-11cos60-15cos60
Fy = 17sin60-11sin60-11sin60+15sin60
fnet = (fx^2+fy^2)^.5
i am not getting the right anwser where am i going wrong

I don't believe the angles involved here are 60 degrees. What would they be?
 

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...
