Ok thank's ! I found 2 picture on the net without explication and I don't understand the result : and it's write : I have the terms highlighted in orange but others I do not understand in particular :

Excuse me jackwhirl I was a little bit confused : So I correct, I would like to define the total force of the system during ascents and descents of the load I have Fa=Fm+Fg+Fi+Ff with Ff=0. I wanted to ask you if Fi=m.a (like in horizontal position) despite the vertical position of the...

We don't need an angle ? For me, the acceleration load isn't the same according to vertical position of the load (on right) and horizontal position (on left). For this formula, For Fi, whathever vertical or horizontal, it is the same formula (a position angle does not count in the...

I would like know the difference between the inertial force when our system is in vertical position (like on right) and the inertial force when our system is in horizontal position (like on left). Because I know with the horizontal positon, we have Fi=m.a but with the vertical position ? Does a...

Hi, How is the inertial force Fi (acceleration) when the system is vertical. I noted Fi_horizontal=m.a, Ff=mg.μ.cos(Θ) et Fg=mg.sin(Θ) .

Ok thank's a lot for your answer ! I had an other question for the acceleration (inertial force). If we machine like drilling, we have an acceleration, then a deceleration during machining. We can decompose their inertial forces with (Fi(acceleration)=m.a and Fi(deceleration)=-m.a ? Or it's an...

Hi I don't understand what Fa mean ? This the weight or no ? And i don't understand too why in the torque TL, we have an additional part with the preload, the internal friction coeff of preload nut ... What is it ? Thanks.
