AI Thread Summary
To calculate the tension in cable winch BD, the mass on the pulley is 200 kg, resulting in a force of 1960 N due to gravity. The tension in the winch may not be equal to this force if the mass is accelerating. Discussions highlight the need to consider the net forces acting on the mass and whether the system is in equilibrium. If there is a difference in tension along the rope, it indicates that additional forces are at play. Understanding these dynamics is crucial for accurate tension calculations in the system.

Homework Statement


Find the Tension in cable winch BD, link to drawing below.

Homework Equations


The mass fixed to the other end of the pulley is 200 kg.

The Attempt at a Solution


I was under the impression that if one side of the pulley pulled down with 1960 N (200 kg * 9.81 ms^-2) then the tension in the winch would be the same as well.
Can anyone shed some light on this?

Is the mass is accelerating? So the forces on the 200 kg mass sum to _____? What are the forces? If there was any difference in the tension of the rope along the rope, what would have to occur?

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...
