  2. Weight transfer - Wikipedia

    en.wikipedia.org/wiki/Weight_transfer

    The major forces that accelerate a vehicle occur at the tires' contact patches.Since these forces are not directed through the vehicle's CoM, one or more moments are generated whose forces are the tires' traction forces at pavement level, the other one (equal but opposed) is the mass inertia located at the CoM and the moment arm is the distance from pavement surface to CoM.

  3. Newton's laws of motion - Wikipedia

    en.wikipedia.org/wiki/Newton's_laws_of_motion

    The forces acting on a body add as vectors, and so the total force on a body depends upon both the magnitudes and the directions of the individual forces. When the net force on a body is equal to zero, then by Newton's second law, the body does not accelerate, and it is said to be in mechanical equilibrium.

  4. Weight distribution - Wikipedia

    en.wikipedia.org/wiki/Weight_distribution

    For this reason weight distribution varies with the vehicle's intended usage. For example, a drag car maximizes traction at the rear axle while countering the reactionary pitch-up torque. It generates this counter-torque by placing a small amount of counterweight at a great distance forward of the rear axle.

  5. Unit load device - Wikipedia

    en.wikipedia.org/wiki/Unit_load_device

    A unit load device (ULD) is a container used to load luggage, freight, and mail on wide-body aircraft and specific narrow-body aircraft. It allows preloading of cargo , provided the containerised load fits in the aircraft, enabling efficient planning of aircraft weight and balance and reduced labour and time in loading aircraft holds compared ...

  6. Force - Wikipedia

    en.wikipedia.org/wiki/Force

    For example, an object on a level surface is pulled (attracted) downward toward the center of the Earth by the force of gravity. At the same time, a force is applied by the surface that resists the downward force with equal upward force (called a normal force). The situation produces zero net force and hence no acceleration.

  7. Ground support equipment - Wikipedia

    en.wikipedia.org/wiki/Ground_support_equipment

    Container loaders, also known as cargo loaders or "K loaders", are used for the loading and unloading of containers and pallets into and out of aircraft. The loader has two platforms which raise and descend independently. The containers or pallets on the loader are moved with the help of built-in rollers or wheels.

  8. Load securing - Wikipedia

    en.wikipedia.org/wiki/Load_Securing

    Some large bundled items or large machinery are placed directly into or onto the transport vehicle for shipment. Load securing functions to hold the unit pallet loads, crates, or other items immobile and secure. An unsecured load can shift in transit and create dangerous dynamics, damaging the cargo and the structure of the vehicle or ...

  9. Power-to-weight ratio - Wikipedia

    en.wikipedia.org/wiki/Power-to-weight_ratio

    Vehicle designs trade off power-to-weight ratio to increase comfort, cargo space, fuel economy, emissions control, energy security and endurance. Reduced drag and lower rolling resistance in a vehicle design can facilitate increased cargo space without increase in the (zero cargo) power-to-weight ratio. This increases the role flexibility of ...
