No, that is 9x 2 = 18 N-m tryingto lift 9 x 3 = 27 N-m moment. The force x distance applied has to be greater
Fulcrum * * * * * The fulcrum is the fixed point. The bar is a lever. Admitedly, it would help if questions were asked properly.
If an object does not move, no work is performed. Work is performed by a force acting through a distance.
you would measure a wall in meters
A 9-N force cannot be applied 2 m from the fulcrum lift the weight because it wouldn't balance
6 x 150 pounds. 900 pounds of force would have to be applied.
The effort force is applied at the handle of the shovel. The fulcrum is where your other hand goes, lower down the shaft, and the fulcrum resistance would be where the load goes on the shovel, I.E the flat bit that you hit people with!
The input force or the effort on a pair of scissors would be the force applied by your hands on the handles. The output force or load would be the blades of the pair of scissors.
No, the function of the fulcrum remains the same The only change would be the ratio of force to load The closer the fulcrum is the the load, the less force required to lift it The farther away the fulcrum is from the load, the more force required to lift it
A seesaw is a basic lever and by definition it has a fulcrum. Without the fulcrum, there would be no point for the seesaw to operate on.
Don't quote me on this but MKG might be an abbreviation for kilogram-meter which would be the torque generated from a 1 kilogram weight horizontally located 1 meter from the fulcrum. This would be roughly equivalent to 9.8 newton meters of torque or 7.23 ft. lbs.
The elbow in the hand is analogous to the fulcrum in a lever
No sweat. Piece o' cake. Bring it on! What's a "nine meter force" ? ?
The fulcrum is the swing hinges and the effort is the seat, you sitting in it would be the load.
If the book holders are shorter than the fulcrum then it can still function are a fulcrum. If the book holders are taller than the fulcrum then it can't function as a fulcrum.
