I am trying to find a formula to determine effort to raise a ladder based on the angle of the ladder at a given time. I am concerned mostly about the angle so I can plug in an individuals height and distance toward the fulcrum. I am assuming the ladder will not slide at the footing. I included a diagram that I hope will help. Ultimately, we are trying to decided between a 2 section 35' extension ladder and a 3 section will have a shorter length when bedded. Thank you.
