Week 4: Free Body Diagrams (Chapter 4) For the following scenarios, draw the Free Body Diagram including the force of gravity, the normal force, and friction; assume that the inclined is at some angle ̘ above the horizontal; include all relevant angles.
1) Draw the free body diagram for a block on a wedge on the floor (not nailed) that is being dragged at 40-degree angle from the incline by an applied force up the incline.
2) Draw a free body diagram for a block on a wedge on the floor (not nailed) that is being pushed upward from behind at a 40-degree angle from the incline by an applied force.
3) Draw the free body diagram for a block on a wedge nailed to a wall. Note nail goes through the both the wedge and the block and is perpendicular to the wedge. Assume base of the wedge is down.
4) Draw the free body diagram for a block on a wedge nailed on a ceiling. Note nail goes through the both the wedge and the block and is perpendicular to the wedge.
