ok. Do you mean something like in this picture? http://imgur.com/A4pX5 http://imgur.com/A4pX5 I only did those two cases because that's what would give Amax and Amin, if its the right way to go. But maybe i should use the force u, and not G like i wrote on there. And the moment doesn't...

So, this problem wasnt really done yet. I also need to find the reaction forces in the center of the disc. Call that point A, and i need to find Amax and Amin reaction forces. Would i be right in trying to find the answer using centripetal force? and combining that with G?

Yaay so then x=238.9 mm Unfortunately i don't have access to the answer right now but doing the same thing on a problem i do have the answer for, were i needed to find the radius instead of the lever arm length, i got the right answer. Its tempting to overcomplicate things (as in trying angular...

So wait.. do i need to multiply u with the radius then and equal that to F*x So u*(D/2)=F*x and break out x from that? And look at it as having to be in equilibrium, only using the new force needed for that acceleration? Or am i just confusing things now?

Hm, am i right in saying that u=167.2N? using g=9.82 m/(s^2)

If the bucket has a uniform acceleration, then a=1.125 m/(s^2)

Thanks for the welcome =) Yes, x is the length of the lever. I have the value of G, F and D D=200mm G=150N F=70N F stays constant and perpendicular to the lever during the movement.

http://imgur.com/NMu80 http://imgur.com/NMu80 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...
