Question:
A 3.0-m-long ladder, as shown in Figure 12.35, leans against a frictionless wall. The coefficient of static friction between the ladder and the floor is 0.40. What is the minimum angle the ladder can make with the floor without slipping?
L= 3.0 m dz Center of mass Tnet = 0 about this point. 60° fs Gravity acts at di the center of mass. ·Static friction prevents slipping.
Step by Step Answer:
Model The ladder is a rigid rod of length L To not slip it must be in both translational ...View the full answer

Take 2 forks and place them on one another in such a way that we can place the coin in between the prongs. Now try to place the coin with forks on the edge of the glass. It will take you some time to adjust the coin on the edge. This requires a little practice to adjust the coin on the edge of the glass. With a little effort, we will see the coin sitting on the edge calmly. If you look closely you will see it wobbling a little bit. The mass is in the handles of the forks so as a low center of mass it stables as it looks.
