Forces acting on Body Moving in a Horizontal Plane
The forces acting on bodies moved in horizontal planes.
The force pushing  or pulling  a body along a horizontal surface can be expressed as
Q = F cos α (1)
where
Q = force moving the body in horizontal direction (N, lb)
α = angle between force F and horizontal plane
The force acting in vertical direction can be calculated as:
P = (F^{2}  Q^{2})^{1/2} (2)
where
P = force acting in vertical direction (N, lb)
Example  Strong Man Pulling a Truck

A "strong man" is pulling a truck by exerting a force of 1000 N. The force is acting 30^{o} to the horizontal plane.
The horizontal force on the truck can be calculated as
Q = (1000 N) cos(30^{o})
= 866 N
= 0.87 kN
The vertical force "lifting" truck can be calculated as
P = ((1000 N)^{2}  (866 N)^{2})^{1/2 }
= 500 N
= 0.5 kN
