Asked by Pablo kesh

a foolish boy remove a nail from a vertical wall by pulling a stick attached to the nail in a direction 30 deg to the wall.
if the tension in the stick is 10cm , calculate the magnitude of the force wich is not effective in pulling out the nail, is it possible to remove the nali thos way if minimum force required is 7N?
why is the boy foolish?
Answered by henry2,
a. Tension = 10 N.
Fx = 10*Cos30 =

b. Fy = 10*sin30 = 5 N. = vertical component of force.
7 N is required.
