AI Thread Summary
To solve the problem of finding the unknown mass on one side of a balance, the key concept is torque. The moments on both sides of the balance must be equal for the system to be in equilibrium. The known variables include the mass of the object on the opposite side, the angle of the balance, and the distances from the fulcrum. The angle does not affect the torque calculation as long as the fulcrum point remains consistent. Understanding these principles will aid in accurately determining the unknown mass.

How would you solve a problem like this. I am assuming its torque. You have to find the mass of the box on the left. Thanks for the help.

I guess it is a continuation, but i just wanted to draw out the problem. I am trying to solve for the unknown mass which is placed on one side of the balance. The things i know are the mass of the object on the other side, the angle the unbalanced balance is at, the distances the objects are from the fulcrum. If I posted incorrectly, forgive me it is my first time, and i will get better. Thanks for all the help

Hi gallimaufry! :smile:

Yes, it's torque (or moment) …

in equilibrium, the moment on each side must be the same

(but the angle makes no difference … the only reason why you have to get the scale arm horizontal when you're weighing is because you must use the same fulcrum point each time, and the fulcrum isn't a perfect point)

TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...

Thread 'Trying to understand the logic behind adding vectors with an angle between them'

My initial calculation was to subtract V1 from V2 to show that from the perspective of the second aircraft the first one is -300km/h. So i checked with ChatGPT and it said I cant just subtract them because I have an angle between them. So I dont understand the reasoning of it. Like why should a velocity be dependent on an angle? I was thinking about how it would look like if the planes where parallel to each other, and then how it look like if one is turning away and I dont see it. Since...
