  2. Moving load - Wikipedia

    en.wikipedia.org/wiki/Moving_load

    In structural dynamics, a moving load changes the point at which the load is applied over time. [ citation needed ] Examples include a vehicle that travels across a bridge [ citation needed ] and a train moving along a track.

  3. Bending of plates - Wikipedia

    en.wikipedia.org/wiki/Bending_of_plates

    Bending of plates, or plate bending, refers to the deflection of a plate perpendicular to the plane of the plate under the action of external forces and moments. The amount of deflection can be determined by solving the differential equations of an appropriate plate theory .

  4. Weigh in motion - Wikipedia

    en.wikipedia.org/wiki/Weigh_in_motion

    Weigh-in-motion or weighing-in-motion (WIM) devices are designed to capture and record the axle weights and gross vehicle weights as vehicles drive over a measurement site. . Unlike static scales, WIM systems are capable of measuring vehicles traveling at a reduced or normal traffic speed and do not require the vehicle to come to a st

  5. Plate theory - Wikipedia

    en.wikipedia.org/wiki/Plate_theory

    The aim of plate theory is to calculate the deformation and stresses in a plate subjected to loads. Of the numerous plate theories that have been developed since the late 19th century, two are widely accepted and used in engineering. These are the Kirchhoff–Love theory of plates (classical plate theory)

  6. Flexural rigidity - Wikipedia

    en.wikipedia.org/wiki/Flexural_rigidity

    The plate elastic thickness (usually referred to as effective elastic thickness of the lithosphere). The elastic properties of the plate; The applied load or force; As flexural rigidity of the plate is determined by the Young's modulus, Poisson's ratio and cube of the plate's elastic thickness, it is a governing factor in both (1) and (2).

  7. Sandwich theory - Wikipedia

    en.wikipedia.org/wiki/Sandwich_theory

    The composite also has a high tensile strength to weight ratio. The high stiffness of the facesheet leads to a high bending stiffness to weight ratio for the composite. The behavior of a beam with sandwich cross-section under a load differs from a beam with a constant elastic cross section.

  8. Vibration of plates - Wikipedia

    en.wikipedia.org/wiki/Vibration_of_plates

    Vibration mode of a clamped square plate. The vibration of plates is a special case of the more general problem of mechanical vibrations.The equations governing the motion of plates are simpler than those for general three-dimensional objects because one of the dimensions of a plate is much smaller than the other two.

  9. Payload fraction - Wikipedia

    en.wikipedia.org/wiki/Payload_fraction

    For this reason, the useful load fraction calculates a similar number, but it is based on the combined weight of the payload and fuel together in relation to the total weight. Propeller-driven airliners had useful load fractions on the order of 25–35%. Modern jet airliners have considerably higher useful load fractions, on the order of 45–55%.
