Question
The two children shown in Figure below are balanced on a seesaw of negligible mass. (This assumption is made to keep the example simple?more involved examples will follow.) The first child has a mass of 26.0 kg and sits 1.60 m from the pivot. a. If the second child has a mass of 32.0 kg, how far is she from the pivot? b. What is Fp, the supporting force exerted by the pivot?
1. CH5 5a Repeat seesaw problem in #15 with the center of mass of the seesaw 0.160 m to the left of the pivot (on the side of the lighter child) and assuming a mass of 12.0 kg for the seesaw. The other data given in #15 remain unchanged. Explicitly show how you follow the steps in the Problem- Solving strategy for static equilibrium)
Explanation / Answer
load * load arm should be same for both the side hence sits at a distance = 26*1.6/32 = 1.3 m support by the fulcrum = 32 +260 *g = 58 * 10 = 580 N FOR THE SECOND PART BALANCE THE NET FORCE N THE MOMENT ABOUT THE FULCRUM TO OBTAIN THE SAME
