not sure i understand what you're saying.

"Not sure I agree with your analysis. Is this a massive uniform bar, no gravity, free to rotate about A? If so, the reaction at A will not equal F. Were that the case, the centre of the bar would not move. I believe the reaction at A will only be F/2. Try, instead, reducing it to a couple...

Haha i myself don't know what the second ques is, now that am reading it, i guess i ate some of the words in the middle, however, i f i am understanding you correctly, you are asking if say while rotating the bar would break off from the constraint at A, what would happen. well in that...

here is the scenario: there are 2 blocks A & B, both have the same mass 'm'. block A is kept on an endless surface. there is no friction between the block A and the surface. now the other block, B, is kept on top of the block A. the coeff of friction between A & B is say 'u'. the limiting...

There is a bar AB. A is fixed and a force F is applied at B perpendicular to the bar. The result of this can be computed by taking equal and opposite forces acting at A perpendicular to the bar (therefore they cancel out and the net force at A is zero, hence this is equivalent to the initial...

DH, DJ british ? and Haruspex, thanks! lol, and DH i think DJ british meant to say the same thing when he said "directly on the COM", please dun give him a hard time, haha. OK i had been pondering over thisthe whole day, looked up some literature and i think i figured it out, one can even...

Does a moment have any real (physical) significance or is it just a definition/ an aid to understand and calculate a couple. Is it that the rotation is actually caused by a couple! I know we can resolve a force causing a moment about a point into a couple and an equal force acting at that...
