AI Thread Summary
To determine the tension in cable ABD and the reaction at support C, it's essential to analyze the forces acting on the frame, particularly focusing on the upward force T and the leftward force T at the respective points. Neglecting friction simplifies the problem, allowing for a straightforward application of equilibrium equations. By summing the moments around the fulcrum and considering the forces acting on the system, the correct tension can be calculated. The discussion concludes with a confirmation that the method used yields the correct answer, aligning with the solution provided in the reference material. Understanding these principles is crucial for accurately solving similar problems in mechanics.

help.. i don't have any idea to solve for the tension so that i could solve for the component force c

Try forgetting that there's a string and a pulley; think instead of a force T acting upward at the LHS of the horizontal part of the frame and a force T acting leftward at the top of the vertical part of the frame.

[Forget also that the leftward force would make the frame slide on the fulcrum! Think of it as a hinge instead]

Can you write the sum of moments?
 
yeah.. thank you.. i got the right answer.. same as the book..
 

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...
