Machine Dynamics: Manual Air Pump Calculation (please check my answer)

AI Thread Summary
The discussion revolves around a problem related to manual air pump calculations that the original poster has been struggling with for a week. They believe they have a solution but feel something is incorrect and seek assistance in identifying the issue. Participants note the image provided is unclear and request the poster to share their calculations as per forum guidelines. There is a debate about the interpretation of the steady velocity of point C, with suggestions that it may refer to tangential speed rather than linear velocity. Overall, the community is eager for clearer details to help resolve the problem effectively.

Summary:: I am stuck into this problem for almost a week now. I think I solved it, but it seems something is wrong. Can someone point me, what is wrong here. It'll be so much helpful.

The image is a bit too fuzzy for me to read. Please type in your working, as required by the forum rules.
 
Should we assume that the mentioned steady velocity of point C is a vector always perpendicular to CO?

I assumed it meant a steady tangential speed, not linear velocity.
I haven't come across this velocity diagram technique before. As far as I can make out, the solution is obtained by measurements from a scale drawing, not by algebra.
 
Thank you, haruspex.
I hope the OP can soon show us his work more clearly.

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...

Thread 'Minimum mass of a block'

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 static friction will act downwards ## \mu Mg \cos \theta ## Now what im confused by is how will we know " how quickly" block B reaches its maximum static friction value without any numbers, the suggested solution says that when block A is at its maximum extension, then block B will start to move up but with a certain set of values couldn't block A reach...
