First condition of equilibrium problem help

AI Thread Summary
To solve the equilibrium problem, the goal is to determine weights w1 and w2 that create a tension of 100 N in a horizontal cable. The component method is suggested for analyzing the forces, particularly focusing on the 30-degree angle of the cable. A free body diagram of the cable joint is essential for performing force balance calculations in both the x and y directions. Understanding that the system is in equilibrium is crucial for applying these principles effectively. Properly setting up the equations will lead to the solution for the weights.

Homework Equations


All I know is the component method but. . .I'm not sure how to apply it here.

The Attempt at a Solution


I really have no idea where to start, so please help!

Since the whole cable setup is not in motion nor is it in impending motion, what must the tension in the cable that makes the 30 degree angle be?

Once you decide on that, draw a free body diagram of the cable joint and perform the usual force balance in the x and y directions.
 

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...
