Lifting
Lifting
(OP)
I want to find out the force required by a person to lift a 10ft x 20ft board that is on the ground at a 20 degree angle. The board weights about 150 lbs. It is fixed on the ground with one end and holding the higher non-fixed end, I want to know if an average adult can push it up to lets say 24 degree angle. Is there a formula to derive the force needed?






RE: Lifting
This is assuming the board in to rigid to deflect under load, i.e. your "fixed" end is actually pinned (free to rotate but fixed from translation) and the board will not bend when lifted.
RE: Lifting
Now you also have to check if its possible to have the board deflect that much without failing, etc.
RE: Lifting
If the end is truly fixed (not free to rotate) then it is as allgood described.
