A crate of weight Fg is pushed by a force P on a horizontal floor.<br />(a) If the coefficent of static friction is µs and P is directed at angle ? below the horizontal, show that the minimum value of P that will move the crate is given by<br /><br />P= µsFgsec?/ 1-µs(tan?)<br /><br />(b) Find the minimum value of P that can produce motion when µs= 0.400
