It is desired to remove the spike from the timber by applying force along its horizontal axis. An obstruction A prevent direct access, so that the two forces, one 1.6 kN and the other P are applied by cables as shown below
(a) Determine the magnitude of P necessary to ensure a resultant T directed along the spike. Also find the magnitude of T
(b) Repeat the calculations in part (a) except the dimension 150 mm is decreased to 50 mm.
