Question

What will happen if the applied force is equal to static friction, limiting friction and kinetic friction?

Answer 1

you need to get something straight.if a stationary body is to move then the force applied must be equal to static friction.so when you are trying to move a stationary object only frictional force coming into play is static friction.and the value of static kinetic and limiting friction is not the same.for this u colud look at the gasph between applied force and friction.so first if applied force equals static friction then body will remain stationary.so in this case the other frictional forces do not come into play at all.

Answer 2

Nothing. The object will not move

Answer 3

if the object is at rest, it will only start to move if the force applied to it exceeds static friction..if the applied force is exactly equal to static friction, then the net force on the object is zero and it will not accelerate (that is, will not change its motion)

Answer 4

If the object is not moving (static) and the applied force is equal to static friction, then the forces cancel and the object will continue not moving.

If the object is moving (kinetic friction applies) and the applied force is equal to kinetic friction, then again the forces cancel. With zero force, there is zero acceleration (F=ma) and the object keeps moving at the same speed.

Limiting friction is really just static friction.
