A homogenous board of 5.0 m in length and 260 N in weight is
lied horizontally on two supports. The left support is located at
the left end of the board and the right support is located at 1 m
from the right end of the board. A person with a mass of 50 kg
stand on the board at a distance of 0.9 m from the right end of the
board. a) Draw the free body diagram of the forces that acted on
the board. b) What is the magnitude of the forces exerted by each
of the supports to the board? c) What is the distance (with respect
to the right end of the board) the person can move so that the left
end of the board starts to lift?
