A homogeneous stick with mass M is placed in a well with smooth surface (see picture). θ is the angle between the stick and the floor.
Determine the force the well gives to the stick.
ΣF = 0
Στ = 0[/B]
The Attempt at a Solution
I draw the free body diagram but I'm not sure
The first body-diagram has normal force 1 is perpendicular to the surface (like common ladder problem)
The second body diagram has normal force 1 is up-left in direction. I think it's because the stair push the wall down-right, it must give the reaction in opposite direction.
Which one is correct ? The first one or the second one ?
