A truck pulls boxes up an incline plane. The truck can exert a maximum force of #6,800 N#. If the plane's incline is #(5 pi )/8 # and the coefficient of friction is #4/5 #, what is the maximum mass that can be pulled up at one time?
The mass is
Resolving in the direction parallel to the plane
Let the force exerted by the truck be
Let the frictional force be
The coefficient of friction
The normal force is
