weightdistribution

Weight distribution describes how the total weight of an object or structure is allocated across its supports or contact surfaces. It is closely related to the center of gravity, the point at which the weight effectively acts. Loads may be dead, live, or dynamic, and can be distributed or concentrated.

In statics, moments determine reactions at supports. The center of gravity position along a chosen axis is x_CG = Σ(W_i x_i)/ΣW_i. For a beam with a uniform distributed load q per unit length, the resultant load acts at the load centroid.

In vehicles, weight distribution between axles affects handling, braking, and stability. Dynamic weight transfer during acceleration, braking, and cornering shifts load toward the opposite axle, altering traction. Designers place components and ballast to achieve a target distribution.

In civil engineering, dead and live loads guide the design of beams, columns, and foundations. Uneven distribution can cause excessive stresses, bending, or settlement.

Measurement and analysis use scales, load cells, and simulations. Finite element analysis helps predict reactions and local stresses, guiding adjustments such as component relocation or ballast addition.

Proper weight distribution enhances safety, performance, and durability in vehicles and structures.
