How Does Newton's Third Law Apply to Stacked Blocks in an Elevator?

AI Thread Summary
In the discussion about stacked blocks in an elevator, the focus is on analyzing the forces acting between the blocks and the floor while the elevator is at rest. The forces include interactions between the three blocks (3kg, 2kg, and 1kg) and the floor. The user attempts to rank the forces from largest to smallest, suggesting that the force of the floor on the 1kg block and the force of the 1kg block on the floor are the largest, followed by the forces between the blocks. Clarification is sought on whether this ranking is correct. Understanding these forces is essential for applying Newton's Third Law in this scenario.

Homework Statement


Three blocks are stacked on top of each other inside an elevator as shown in the figure.
Answer the following questions with reference to the eight forces defined as follows.

the force of the 3kg block on the 2kg block, F of 3 on 2,
the force of the 2kg block on the 3kg block, F of 2 on 3,
the force of the 3kg block on the 1kg block, F of 3 on 1,
the force of the 1kg block on the 3kg block, F of 1 on 3,
the force of the 2kg block on the 1kg block, F of 2 on 1,
the force of the 1kg block on the 2kg block, F of 1 on 2,
the force of the 1kg block on the floor, F of 1 on floor, and
the force of the floor on the 1kg block, F of floor on 1.

Assume the elevator is at rest. Rank the magnitude of the forces.
Rank from largest to smallest.

Thread 'Voltmeter readings for this circuit with switches'
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 'Struggling to make relation between elastic force and height'
Hello guys this is what I tried so far. I used the UTS to calculate the force it needs when the rope tears. My idea was to make a relationship/ function that would give me the force depending on height. Yeah i couldnt find a way to solve it. I also thought about how I could use hooks law (how it was given to me in my script) with the thought of instead of having two part of a rope id have one singular rope from the middle to the top where I could find the difference in height. But the...
