AI Thread Summary
The energy stored in a steel cable used for towing gliders is minimal due to its limited stretch, which is intentional to ensure safety. The discussion highlights that a low energy storage is preferable to prevent dangerous situations when the cable breaks or is released. An equation related to energy storage in springs is mentioned, but the focus remains on the practical implications of energy retention in cables. The safety concerns of high energy storage in towing scenarios are emphasized. Overall, the design of towing cables prioritizes safety by minimizing energy storage.

Energy stored in a cable?? (A Level CW)

Why is the energy stored in a steel cable used for towing gliders so small? And is there an equation that could show this?

It's the energy store in a spring.
The cable doesn't stretch very much - that's deliberate so that there isn't much energy stored.

What are your thoughts? We do not do your homework for you here on the PF.

Well, I can think of a good reason why the two pilots would not want a lot of energy stored in that cable...
 


Think of what happens when that cable does break.

..or is simply released, as per routine.
 

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...
