PHYS 152 - WW4B Normal Forces Rank these situations in order of increasing Magnitude of Normal Force exerted on the object. In each case the object has a weight of 10 N. Explain/justify your ranking. Describe the direction of the normal force in each case. You must adhere to the assignment structure document. For the 10N object in the diagram, determine the normal force between the block and the ceiling. Free Body Diagram Coord Sys ceiling (E) Force Table Block 45% 40N For this situation I can identify interactions so I know there are exerted on the block. I am asked to find the which is the component of the force. It is thus a good idea to treat the contact force as forces, the force and the force, instead of a single force. Including these forces I should have forces on my free body diagram. I know the block is not so I can say it is in so the net IS Knowing this I should check that the graphical sum of my in my add to zero. Now I write: Fret =Since I am trying to nd the it is convenient for me to rotate my by degrees so that the normal force is the direction. I can now rewrite my net force expression in with respect to my chosen coordinate system as: fr: r'lEII' The net force is so both the and components must be zero. Since I am using a coordinate system I can determine the magnitude of the force considering only the terms in the direction and determine the normal force is N in the
