Simple static equilibrium problem

AI Thread Summary
A 70kg mass suspended from two cords at angles of 40 and 30 degrees creates a static equilibrium problem. The weight of the mass is calculated to be 686N. To determine the tension in each cord, one must sum the forces in both the x and y directions, resulting in two equations with two unknowns. This approach allows for the calculation of how much load each cord supports. Understanding these principles is essential for solving static equilibrium problems in physics.

A 70kg mass is suspended from two cords. One is at 40 degrees with the cieling, and the other is at 30 degrees. What is the tension in both cords?

I got the weight of the object, which is 686N, but how does one know how much of the load each cord supports? I missed this particular physics class. I know, it is an extremely simple question. Any help is appreciated.

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...
