The figure shows an empty wheelbarrow which
weighs 80 N.
The operator pulls upwards on the handles with a
force of 20 N to keep the handles horizontal.
The point marked M is the centre of mass of the
wheelbarrow.
a) draw arrows to show the other two vertical forces that act on the wheel barrow
b) determine
i)the moment of the 20 N force about the centre of the wheel A
ii) the distance between points A and M
