1. Effective force pulling the nail out of the wall (F_effective):
The effective force can be found by resolving the force applied at an angle to the vertical direction. In this case, the force applied is 80N and it makes an angle of 60 degrees with the horizontal.
We can use trigonometry to find the component of the force in the vertical direction (F_vertical):
F_vertical = F_applied * sin(angle)
F_vertical = 80N * sin(60 degrees)
F_vertical = 80N * √3 / 2
F_vertical ≈ 69.28N
So, the effective force pulling the nail out of the wall is approximately 69.28N.
2. Force that bends the nail (F_bend):
The force that bends the nail can be found by resolving the force applied at an angle to the horizontal direction.
We can use trigonometry to find the component of the force in the horizontal direction (F_horizontal):
F_horizontal = F_applied * cos(angle)
F_horizontal = 80N * cos(60 degrees)
F_horizontal = 80N * 1 / 2
F_horizontal = 40N
So, the force that bends the nail is 40N.
Therefore, the effective force which tends to pull the nail out of the wall is approximately 69.28N and the force which bends the nail is 40N.
