A man attempts to support a stack of books horizontally by applying a compressive force of F
Question:
A man attempts to support a stack of books horizontally by applying a compressive force of F = 120N to the ends of the stack with his hands. If each book has a mass of 0.95 kg, determine the greatest number of books that can be supported in the stack. The coefficient of static friction between the man?s hands and a book is (?s)h = 0.6 and between any two books (ms)b = 0.4.
F = 120 N F = 120 N
Step by Step Answer:
Equations of Equilibrium and Friction Let n be the number of books that are on the v...View the full answer

In Physics, a force is an influence that can change the motion of an object. A force can cause an object with mass to change its velocity, i.e., to accelerate. Force can also be described intuitively as a push or a pull. A force has both magnitude and direction, making it a vector quantity. In this video, the concept of force and torque is demonstrated with the practical application of changing the flat tire of the car.
