AI Thread Summary
The discussion revolves around calculating the horizontal acceleration of a system involving a wheel and masses, where the wheel rolls without slipping. The user identifies that mass m3 is influenced by gravity, which causes the wheel with mass m2 to turn and propel mass m3 forward. Key considerations include the gravitational force acting on m3 and the total mass of the system, which consists of m1, m2, and m3. The moment of inertia of the wheel is also a critical factor in determining the acceleration. The user seeks urgent assistance in solving this problem, particularly regarding the incorporation of the moment of inertia.
Kindly see the attached pdf. My attempt to solve it, is in it.
I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction.
I'm not able to figure out, why my solution is wrong, if it is wrong .
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...
Here is what I tried
This question was actually asked in one of our engineering entrances.
The answer was 1D.
My teachers say that we have to use μₘ/fₘ to get to this answer. I cannot understand why. I'll be really glad if you could tell me the exact definition of power (numerically) that works in all scenarios.
