    Curve Train
AI Thread Summary
When a train navigates a curve, the wheels on both sides rotate at the same speed, but the inner rail has a smaller curvature than the outer rail. This means the outer wheel must cover a longer distance than the inner wheel. The phenomenon occurs because the inner wheels can slip on the rail, allowing for this difference in distance without requiring banking of the track. The discussion highlights the mechanics of wheel rotation and rail interaction during curved travel. Understanding this concept is crucial for grasping train dynamics in curved sections of track.

Hello,
Please help me to find out the answer for the following question...!
When a train is running, wheels at both sides are rotating with a same
speed . So when it runs through a curve, the inner rail is having a small curvature than the outer rail. So Outer wheel has to travel a long distance than the inner wheel . So if both side's wheels are running with same speed, how it happens ? What is the magic here. Is it realted with Banking of curvature concepts. Please, anybody can provide some expert opinions for the above question..?
Thanks in advance..!:cool:

No banking is necessary. The inner wheels slip on the rail.
 

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 'Collision of a bullet on a rod-string system: query'

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

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...
