Hi Tom, I don't think your formula is true, in the sense that the 60 inches up it must travel is in an arc, therefore it won't be exactly a 100% angle, as 60 inches around an arc will not cause the 60 inch long platform to go up to a 90 degree angle.
I may be wrong, but I don't think I am. What say you others on this? Victor Co-moderator Blind Movie Buffs List Guidedogs List
