Like.
That's what it reads because the OP does not realize that the diagram illustrates the special case of equal masses. The OP assumes that... -
Lnewqban replied to the thread Problem with pulleys - two fixed and one movable.Understood, but it seems not to be a special case because it reads "The diagram of the problem is shown to the right." The OP may...

Lnewqban replied to the thread Problem with pulleys - two fixed and one movable.Aren't the relative accelerations given in the OP's diagram? I see 2a for m1 and m2, as a for M.

That is wrong. The above equation (which I'll call equation A) doesn't follow from the other equations. Consider your (correct)...

I went with the stake-and-shim. The shim is steel, with a 90 degree bend, so I can pound it in with the fulcrum hammer. It does...

Ok. Suppose the top vertical scale was directly connected to the rigid (but massless) pulleys and frame like this:

Lnewqban replied to the thread B What is the Correct Reading on the Scale in This Mass/Scale Puzzle?.Strain on a section under tension that finally yields, is acting on both axial directions, increasing the length, and trying to separate...

Refer to the original diagram in post #1. Fact: The hanging mass on the left is and remains at rest. This means that the tension in the...

Consider the drawing shown on the right. The tension in the left string is equal to the weight, T = 100 N because the mass is at rest...
