... 3) If you stand on a pair of bathroom scales, explain how the readings change as you shift your weight gradually from side to side. What rule governs the readings on the scales? Answer: The equilibrium rule guides the scale readings. That is, the total of the readings adds to equal your weight. The ...

... in equation 6.1 accomodates for this. Figure 6.5 shows the path taken by a particle moving from A to B in three dimension space. At a particular point, the force, F, is being applied over displacement dr, and this is shown. It is clear that F is not inline with the direction of motion (indicated by ...

... What dimensionless groups can be constructed for the drag problem? For the drag problem, form dimensionless groups from among the goal quantity F and the quantities on which F depends: v, ρ, ν, and r. One group is F/ρv2 r2 , as you can check by working out its (lack of) dimensions. A second group is ...

... A certain string can withstand a maximum tension of 9.0 N. without breaking. A child ties a 0.82 N. stone to one end. Holding the other end, he whirls the stone in a vertical circle of radius 3.0 m slowly increasing the speed until the string breaks. (a) Where is the stone on its path when the strin ...
