Load Capacity
The maximum amount of weight or force that a structure, vehicle, system or material can safely bear without compromising its integrity or functionality.
Load Capacity
Load capacity represents the upper limit of stress that can be applied to a system before it experiences failure or unsafe operating conditions. This fundamental concept is essential across numerous engineering and design applications.
Core Components
Types of Loads
- Static loads: Constant forces like the weight of a building
- Dynamic loads: Variable forces such as vibration or wind resistance
- Point loads: Forces concentrated at specific locations
- Distributed loads: Forces spread across an area or length
Safety Factors
Load capacity calculations typically incorporate safety margin considerations:
- Design capacity vs. actual capacity
- Material fatigue allowances
- Environmental condition variations
- Emergency situation buffers
