It is desired to remove the spike from the timber by
applying force along its horizontal axis, An obstruc-
tion A prevents direct access, so that two forces, one
1.6 kN and the other P, are applied by cables as
shown. Compute the magnitude of P necessary to
ensure a resultant T directed along the spike. Also
find T.
