Thank you for your time.
I can think of 1)Increasing the height of the stand holding the
ball 2) Use a heavier ball.Doing all these will increase the
gravitational potential energy which will push the wooden disc
higher.
How about moving the fulcrum nearer to the wooden disc?Does it
helps.Please help to explain.
An easier method without changing anything is to move the
fulcrum. Move it closer to the metal stand so that the dist between
the fulcrun and the effort is less than the dist between the
fulcrun and the load. This will increase the amount of force on the
load with equal effort use if i didn't remember it wrongly.
