Resolving Horizontal Force F: Explanation and Process

AI Thread Summary
The discussion centers on resolving a horizontal force F into components along different members. It highlights that the components of force F can vary based on the chosen coordinate system. The blue triangle's representation suggests a non-Cartesian system where axes are not perpendicular, leading to different results compared to the red triangle. Understanding the coordinate system is crucial for accurate force resolution. Properly identifying the axes will ensure consistent and correct component calculations.

Ok, this is a stupid question, but which way can I resolve the force F acting horizontally?

If I want to resolve the force F along the black member, then why does force along the black member if resolved using the blue triangle differ from the resolving down the member from the red triangle?

Thanks :)

If F is the vector you want to resolve into components, then those components will be different for different coordinate systems.

It would appear that for your blue triangle, if the blue lines are meant to represent components, that the coordinate system is non-Cartesian in that the axes are not perpendicular.

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...
