Hello!
I have a problem to solve and I am not quite sure how to.
In the linked image i have the values of G, F and D given.
F stays constant and right angled towards the lever.
The bucket needs to go up 9 meters in 4 seconds.
What is the smallest x can be for this to happen?
I know how to find x if the system was standing still, or at constant speed.
But it needs to move the bucket up 9 meters in 4 seconds.
Since the only thing i can change is x i presume that the extra moment given by extra length of x, correlates to the speed it needs to have?
Or can i look at this as a constant speed problem by saying that from the start of the movement, there was an average speed of 2.25 m/s?
Which then would mean that the length of x is equal to what it would be if the system was standing still.
As in
G*(D/2)-F*x=0
if using the center of the disc as the moment point.
Im confused.
Can i solve this simply through equilibrium analyzes or do i have to involve angular momentum or something like that?
Sry if my english isn't the best. Its not my native language.
