    Equilibrium Load
AI Thread Summary
To achieve equilibrium on a 6.0 m bar supported at 3.9 m from the left end, the load on the right end must balance the moment created by the 468 N load on the left. The moment equation M=Fd indicates that the distance from the fulcrum to each load is crucial for calculating the necessary right-end load. The participant seeks guidance on applying this equation correctly, suggesting that a sketch and detailed work may reveal a simple arithmetic error. Understanding that the downward force must equal the upward force is essential for solving the problem. Proper application of the moment equation will lead to the correct load needed for equilibrium.

Homework Statement


A 6.0 m bar is supported by a fulcrum at 3.9 m from the left end. There are loads applied to each end of the bar. The load at the left end of the bar is 468 N. What load in Newton should be applied to the right end of the bar to create equilibrium?

Homework Equations


M=Fd

The Attempt at a Solution


I attempted to solve the solution by using a sketch and the M=Fd equation but for some reason I cannot figure out how to create equilibrium. I know that the downward force must = upward force? I would really appreciate just a little bit of guidance and I'm sure a light will go off up there!

Well, show us your sketch and your work with the moment equation. It might be just a simple arithmetic mistake.
 
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...
