A crate of weight Fg is pushed by a force on a horizontal floor. (a) If the coefficient of static friction is µs, and is directed at angle below the horizontal, show that the minimum value of P that will move the crate is given by the following equation. P=[UsFgsec(theta)]/[1-Ustan(theta)] (b) Find the minimum value of P that can produce motion when µs = 0.335 and Fg = 145 N for the following angles. I dont understand what do they want me to do in the beginning!!
