An 20 kg plank leans on a rough floor, against a frictionless wall, making an angle of 40 degrees with the horizontal. An 7 kg mass hangs down at a distance of 7 meters from the top end of the plank. Determine all the forces (direction and magnitude) acting on the plank, assuming the plank is in both rotational and also translational (linear) equilibrium, then determine the implied value of the coefficient of static friction of the floor against the...
