Answer to Question #149001 in Physics for Alabija Isaac

Question

a nail on a vertical wall is pulled by means of a cord attached to his head if he called make an angle of 60 degree to the horizontal it exerts the force of 18 Newton on the nail a. Find the effective force which tends to pull the nail out of the wall b. Find the force which tends to bend the nail

Answer 1

a)

$$F_x=F\cos{60}=18\cos{60}=9\ N$$

b)

$$F_y=F\sin{60}=18\sin{60}=15.6\ N$$
