The previous step focused on friction for horizontal surfaces. As we discussed above, angled surfaces like the wedge below have different considerations. FN = mg cos(0) F₁ = mg F₁ = ? F₁ = ? Fy=mg cos(0) Specifically, we have the following considerations. 1. The normal force is not equal to mg. 2. There is a force acting along the angle of the wedge due to gravity. What is the coefficient of static friction ? Fx = mg sin(0) Let's consider the implications of this type of problem with the following examples. For all of the examples, the box has a mass of 25 kg. Imagine the box is on a surface that allows you to adjust the incline angle, 0. You find the maximum angle where the box remains stationary. That is, at any higher angle, and the box begins to slide. The static friction force at this maximum angle is 150 N. What is the angle 0 (in degrees)? Now you raise the incline to an angle of 60° greater than the angle of maximum static friction found above. At this angle, the box slides…

Directions: Write TRUE is the statement is correct but if it is false, change the underlined words with the correct answer. 1. A force is a push or pull 2. Force is a galar quantity 3. The unit of force is Newton (N) 4. In general, a body can have several forces acting on it at the same time 5. Inertial frame of reference are reference frame where Newton's First law are observable. 6. Another effect of a balanced force, equilibrium, is that a body accelerates. 7. The heavier the object, the lesser the inertia. 8. Forces acting on a body are unbalanced if the resultant force is not zero 9. In an inertial reference frame, No forces should be exerted within the frame. 10. Normal force is lateral in nature. П.
