Resultant of three forces about a point O

AI Thread Summary
To find the resultant of three forces about point O, first calculate the x and y components of each force, then determine the magnitude by squaring and taking the square root of the sum of these components. The discussion raises a question about how to find the perpendicular and horizontal distances after calculating the resultant. There is a concern about potential misinterpretation of the teacher's instructions regarding the study guide, which mentions 2-D moments. Clarification is needed on the specific problem and the approach being used, as well as the difficulties encountered. Understanding the correct application of these concepts is essential for solving the problem effectively.

My question is to find the resultant just take the x,y components of each force, find the magnitude by squaring them and taking the square root. My question is after doing that how would i find the perpendicular and horizontal distances.

My teacher put a study guide for our test and it said resultant of 3 forces about a point, 2-D, 2-D moments.

Maybe i misinterpreting what he really wants?

The picture is not the actual problem just an example.

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'

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...
