3. The pruning mechanism of a pole saw is shown as it cuts a branch S. For the particular position drawn, the actuating cord is parallel to the pole and carries a tension of 30 lb. Determine the shearing force P applied to the branch by the cutter, the total force supported by the pin at E and the force exerted by member CD. The force exerted by the light return spring at C is small and may be neglected.
