2. Fixed end moment - Wikipedia

   en.wikipedia.org/wiki/Fixed_end_moment

   The fixed end moments are reaction moments developed in a beam member under certain load conditions with both ends fixed. A beam with both ends fixed is statically indeterminate to the 3rd degree, and any structural analysis method applicable on statically indeterminate beams can be used to calculate the fixed end moments.

3. Rigid frame - Wikipedia

   en.wikipedia.org/wiki/Rigid_frame

   If K s L/EI ≥ 20, it is acceptable to consider the connection to be fully restrained (in other words, able to maintain the angles between members). If K s L/EI ≤ 2, it is acceptable to consider the connection to be simple (in other words, it rotates without developing moment). Connections with stiffnesses between these two limits are ...

4. Moment distribution method - Wikipedia

   en.wikipedia.org/wiki/Moment_distribution_method

   When a joint is released, balancing moment occurs to counterbalance the unbalanced moment. The balancing moment is initially the same as the fixed-end moment. This balancing moment is then carried over to the member's other end. The ratio of the carried-over moment at the other end to the fixed-end moment of the initial end is the carryover factor.

5. Macaulay brackets - Wikipedia

   en.wikipedia.org/wiki/Macaulay_brackets

   Macaulay's notation is commonly used in the static analysis of bending moments of a beam. This is useful because shear forces applied on a member render the shear and moment diagram discontinuous. Macaulay's notation also provides an easy way of integrating these discontinuous curves to give bending moments, angular deflection, and so on.

6. Cantilever - Wikipedia

   en.wikipedia.org/wiki/Cantilever

   The end fixed rigidly to the central fuselage is known as the root and the far end as the tip. In flight, the wings generate lift and the spars carry this load through to the fuselage. To resist horizontal shear stress from either drag or engine thrust, the wing must also form a stiff cantilever in the horizontal plane.

7. Shear and moment diagram - Wikipedia

   en.wikipedia.org/wiki/Shear_and_moment_diagram

   Shear and Bending moment diagram for a simply supported beam with a concentrated load at mid-span. Shear force and bending moment diagrams are analytical tools used in conjunction with structural analysis to help perform structural design by determining the value of shear forces and bending moments at a given point of a structural element such as a beam.
