Inertia refers to the principle that a stationary object Inertia refers to the principle that a stationary object
remains stationary as long as there is no external remains stationary as long as there is no external
force acting to move it, and that a moving object force acting to move it, and that a moving object
continues moving at a constant speed as long as continues moving at a constant speed as long as
there is no external force acting to stop it. there is no external force acting to stop it.
When the lift truck starts to move there is a When the lift truck starts to move there is a
momentary backward force (resistance to moving) momentary backward force (resistance to moving)
due to inertia, and when it stops there is a due to inertia, and when it stops there is a
momentary forward force (resistance to stopping). momentary forward force (resistance to stopping).
As a result, if As a result, if the brakes are applied the brakes are applied
the truck is traveling in reverse, the backward force the truck is traveling in reverse, the backward force
will become strong enough to tip the truck over will become strong enough to tip the truck over
backward. Likewise, when the truck is turning there backward. Likewise, when the truck is turning there
is a centrifugal force that pulls it outward from the is a centrifugal force that pulls it outward from the
turning center. This force can cause the truck to tip turning center. This force can cause the truck to tip
over sideways. Since the zone of sideways stability over sideways. Since the zone of sideways stability
