  2. Working load limit - Wikipedia

    en.wikipedia.org/wiki/Working_load_limit

    Working Load Limit (WLL) is the maximum working load designed by the manufacturer. This load represents a force that is much less than that required to make the lifting equipment fail or yield. The WLL is calculated by dividing MBL by a safety factor (SF).

  3. Ultimate load - Wikipedia

    en.wikipedia.org/wiki/Ultimate_load

    In engineering, the ultimate load [1] is a statistical figure used in calculations, and should (hopefully) never actually occur.. Strength requirements are specified in terms of limit loads (the maximum loads to be expected in service) and ultimate loads (limit loads multiplied by prescribed factors of safety).

  4. Euler's critical load - Wikipedia

    en.wikipedia.org/wiki/Euler's_critical_load

    The critical load is the greatest load that will not cause lateral deflection (buckling). For loads greater than the critical load, the column will deflect laterally. The critical load puts the column in a state of unstable equilibrium. A load beyond the critical load causes the column to fail by buckling. As the load is increased beyond the ...

  5. Factor of safety - Wikipedia

    en.wikipedia.org/wiki/Factor_of_safety

    The design factor is defined for an application (generally provided in advance and often set by regulatory building codes or policy) and is not an actual calculation, the safety factor is a ratio of maximum strength to intended load for the actual item that was designed.

  6. Ultimate tensile strength - Wikipedia

    en.wikipedia.org/wiki/Ultimate_tensile_strength

    The reversal point is the maximum stress on the engineering stress–strain curve, and the engineering stress coordinate of this point is the ultimate tensile strength, given by point 1. Ultimate tensile strength is not used in the design of ductile static members because design practices dictate the use of the yield stress. It is, however ...

  7. Structural load - Wikipedia

    en.wikipedia.org/wiki/Structural_load

    Limit loads are the maximum loads a component or structure may carry safely. Ultimate loads are the limit loads times a factor of 1.5 or the point beyond which the component or structure will fail. [11] Gust loads are determined statistically and are provided by an agency such as the Federal Aviation Administration.

  8. Maximum power transfer theorem - Wikipedia

    en.wikipedia.org/wiki/Maximum_power_transfer_theorem

    The red curve shows the power in the load, normalized relative to its maximum possible. The dark blue curve shows the efficiency η. The efficiency η is the ratio of the power dissipated by the load resistance R L to the total power dissipated by the circuit (which includes the voltage source's resistance of R S as well as R L):

  9. Yield (engineering) - Wikipedia

    en.wikipedia.org/wiki/Yield_(engineering)

    Yield Point Elongation (YPE) significantly impacts the usability of steel. In the context of tensile testing and the engineering stress-strain curve, the Yield Point is the initial stress level, below the maximum stress, at which an increase in strain occurs without an increase in stress.
