A stone is balanced horizontally on a 4 m long board with a mass of 25 kg according to the figure below. The center of gravity of the stone is on a line tangential to the left end of the plank and the horizontal distance between the center of gravity of the stone and the point of rotation is 2.8 m. Calculate the mass of the stone. the pressure on the other side of the stone has F=3kN
