Question
A man attempts to support a stack of books horizontally
by applying a compressive force of F = 120 N 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(μs)h = 0.6 and between any two books (μs)b = 0.4.
