To solve for the x' and y component forces from a 360N force acting along the leg, one can utilize trigonometry by drawing right-angled triangles. The components can be calculated using the formula F_x = F * cos(theta) and F_y = F * sin(theta), where theta is the angle between the force and the axis. The discussion also inquires about recommended textbooks that cover these concepts in detail. The original post dates back to 2013, indicating limited engagement from the member. Understanding these principles is essential for applications in biomechanics, especially in surgical contexts like knee joint replacement.

The original post is from 2013 and the member made only the one post. It is rather unlikely that they will ever be back to answer your query.uniqueda said:
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...
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
$$T + f_f - N_w = Ma$$

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.
