tellmesomething replied to the thread Minimum mass of a block.I apologise, I should have been more careful -
It seems a lot of confusion is created for the OP when the full original problem statement is not provided. The learner may not be able...
-
This problem can be solved in four steps: Find an equation for the threshold critical tension ##T_{crit.}## at which block B will start...

tellmesomething replied to the thread Minimum mass of a block.It was only when I read post #3 that this point was clear to me, i wasn't thinking this way earlier..

tellmesomething replied to the thread Minimum mass of a block.Yes this was the intended question , my instructor wrote it in class on the blackboard and then he just solved it, this was the diagram...
-
The intended original question is probably something like this: Block B (mass ##M##) is initially at rest, in equilibrium, on the...
-
tellmesomething replied to the thread Minimum mass of a block.do you mean as in the weight component of block B along the inclined plane exceeds even the maximum static friction? this is before...
-
I’m not entirely sure what the difficulty is, but this might help... Imagine gradually adding weights to to A, i.e. gradually...
-
tellmesomething replied to the thread Minimum mass of a block.But since we are increasing the mass gradually, aren't we sure that only at the maximum extension of the spring we will get a new...
-
PS if we are being totally precise, doing the mathematical calculation, we will find the maximum mass of A that will not move block B...
-
Let's fix the mass of block B (##M##). Start with a small mass of block A ##m##. This moves up and down. The maximum force in the...
-
What has the spring to do with it? When the system is released from rest, is the spring relaxed, at equilibrium with its suspended...
-
tellmesomething replied to the thread Minimum mass of a block.The spring is relaxed when the system is released from rest. Yes... Yes i do mean that, sorry for the wording. After reading post #3...
-
Here we know that if block B is going to move up or just be at the verge of moving up ##Mg \sin \theta ## will act downwards and maximum...

I believe it was the summer of 2001 that I made a trip to Peru for my work. I was a private contractor doing automation engineering and...
