    Automotive Law
AI Thread Summary
Lenz's law is evident in automotive electrical systems when additional loads, such as windshield wipers, are activated. This results in the alternator experiencing counter torque, necessitating increased fuel consumption to maintain vehicle speed. The alternator's output current generates a torque that opposes the engine's torque via the belt system. This phenomenon illustrates Lenz's law, where induced quantities, like torque and current, are oriented opposite to their original quantities. Understanding this relationship is crucial for comprehending the efficiency and performance of automotive electrical systems.

I kind of understand Lenz's law but was wondering if anyone could tell me were does lenz's law acutally occur in automotive electrical systems.?

When a load is added, like turning on the windshield wipers, the alternator incurs a counter torque. In order to maintain the same vehicle speed, more fuel must be burned. The alternator output current results in a torque which opposes the torque from the engine through the belt. This is an example of Lenz' law. Induced quantities are oriented in an opposite direction to the original quantities, i.e. torque, flux, current/mmf, voltage/emf.

Thread 'Question about pressure of a liquid'

I am looking at pressure in liquids and I am testing my idea. The vertical tube is 100m, the contraption is filled with water. The vertical tube is very thin(maybe 1mm^2 cross section). The area of the base is ~100m^2. Will he top half be launched in the air if suddenly it cracked?- assuming its light enough. I want to test my idea that if I had a thin long ruber tube that I lifted up, then the pressure at "red lines" will be high and that the $force = pressure * area$ would be massive...

Thread 'Why is the 3 body problem unsolvable? And what will happen if someone solves it?'

I feel it should be solvable we just need to find a perfect pattern, and there will be a general pattern since the forces acting are based on a single function, so..... you can't actually say it is unsolvable right? Cause imaging 3 bodies actually existed somwhere in this universe then nature isn't gonna wait till we predict it! And yea I have checked in many places that tiny changes cause large changes so it becomes chaos........ but still I just can't accept that it is impossible to solve...
