A person is lying on a board, which is supported at both ends. A vertical
reaction force
V
A
is acting on the board at point A and passes through the
origin of the coordinate system. A vertical reaction force
V
B
is acting at the
point located in
x
B
=
e
x
. It is known that the weight of the person is
F
and the weight of the board is
P
. The vector that determines the centroid C
of the person is given by:
