SUMMARY

The discussion centers on the interpretation of angles in relation to forces acting on an angled piece of metal. Specifically, the force at point B is perpendicular to the metal, which is inclined at a 20-degree angle to the vertical. Consequently, the angle that the force makes with the horizontal is indeed 20 degrees, not 70 degrees, as the vertical and horizontal angles are complementary. This clarification resolves the confusion regarding the relationship between the angles of the force and the metal.

At the point B, there is supposed to be a force B that is perpendicular to the angled piece of metal. Why is the angle that the force makes with the horizontal 20? Should it not be 70?
