A truck pulls boxes up an incline plane. The truck can exert a maximum force of #5,700 N#. If the plane's incline is #(2 pi )/3 # and the coefficient of friction is #8/5 #, what is the maximum mass that can be pulled up at one time?
So, we want to know the maximum mass of the boxes.
This is because when the boxes reach the maximum mass, the truck at this stage cannot pull more boxes. Thus, the force that pulls everything up the incline must be equal to the forces against the motion.
The problem is that
Rearrange the equation to get
Now plug in the numbers to get
Now use that equation
After you plug in the numbers you will get :
