You try to push a crate of weight M with a force F on a horizontal floor. The
coefficient of static friction is μs, and you exert the force F under an angle φ below the
horizontal.
Determine the minimum value of F that will move the crate.
Okay so basically what i did was equate Mμs=Fcos φ and evaluate for F. however the answer my teacher gave me is slightly different. He use Nμs=Fcos φand he found N by evaluating the forces in the y component. So the question is why can't i just equate the force applied with the static friction?
