Mechanical load refers to the external forces or weights applied to a structure or material. This can include tension, compression, bending, and shear forces that affect how the material behaves under stress. Understanding mechanical load is crucial in fields like engineering and construction, as it helps ensure that structures can support the intended weight and forces without failing. When designing objects like bridges or buildings, engineers must calculate the mechanical load to ensure safety and stability. Factors such as the material's strength, shape, and the environment play a significant role in how it will respond to these loads. Proper assessment helps prevent structural failures and accidents.
