A truck pulls a trailer on a flat stretch of road. The forces acting on the trailer are
the force due to gravity (250 000 N downward), the force exerted by the road
(250 000 N upward), and the force exerted by the cable connecting the wailer to
the truck (20 000 N to the right). The forces acting on the truck are the force due to
gravity (80 000 N downward), the force exerted by the road (80 000 N upward), the
force exerted by the cable (20 000 N to the left), and the force causing the truck to
move forward (26 400 N to the right).

The net vertical force on the trailer is 0, while the net horizontal force on the trailer is 20,000 N to the right.

The net vertical force on the truck is 0, while the net horizontal force on the truck is 6,400 N to the right.

The given parameters;

the trailer:

  • force on the trailer due to gravity, Fg = 250,000
  • normal force on the trailer due to the road, N = 250,000 N
  • horizontal force on the trailer, Fx = 20,000 N to the right

the truck:

  • force on the truck due to gravity, Fg = 80,000 N
  • normal force on the truck due to the road, N = 80,000 N
  • left horizontal force on the truck, Fx = 20,000 N
  • right horizontal force on the truck, Fx = 26,400 N

The net force on each vehicle is calculated as follows;

for the trailer:

Net vertical force is calculated as;

[tex]\Sigma F_y = 250, 000 \ N - 250,000 \ N = 0[/tex]

Net horizontal force is calculated as;

[tex]\Sigma F_x = 20,000 \ N[/tex]

for the truck;

Net vertical force is calculated as;

[tex]\Sigma F_y =80,000 \ N - \ 80,000 \ N = 0[/tex]

Net horizontal force is calculated as;

[tex]\Sigma F_x = 26,400 \ N - \ 20,000 \ N = 6,400 \ N \ to \ the \ right[/tex]
