Each description below indicates the object of interest via bold italics. Draw a picture of the situation, in which you identify contact points. Then, following the same steps outlined above, draw a FBD on the object of interest. All forces should be written as above ( Fobject 1 -object 2). Make sure the lengths of the arrows are representative of the magnitudes ofthe forces you draw, All forces need to have the origin on the ul i-f interest, Picture of the situation: identify contact points FBD for object of interest A book is at rest sitting on a table A car is at rest on a ramp Created by Alexandru Marics 2018 4-2
