Question:
A book of mass M?is positioned against a vertical wall. The coefficient of friction between the book and the wall is ?. You wish to keep the book from falling by pushing on it with a force F?applied at an angle ??with respect to the horizontal (??/2 2), as shown in Fig. For a given ?, what is the minimum F?required? What is the limiting value of ?, below which there does not exist an F?that will keep the book up?
M
Step by Step Answer:
The normal force from the wall is F cos so the fricti...View the full answer
