why it's 4(2/3)=8/3 ?SteamKing said:
You might want to look more carefully at the diagram in the OP, Figure E4.10. This shows the layout of the entire beam and the load.chetzread said:
"Restriction of moment at wall" refers to the principle of limiting or controlling the amount of rotational force or torque that can be exerted on a wall or structure. This is important for maintaining the structural integrity and stability of buildings and other constructions.
"Restriction of moment at wall" is important because excessive moments or rotational forces on a wall can cause it to fail or collapse, leading to potential safety hazards and costly repairs. By limiting the moments at a wall, the structure can remain stable and strong.
"Restriction of moment at wall" is typically achieved through the use of reinforcement techniques such as adding steel beams, braces, or other support structures to distribute the load and reduce the amount of moment at the wall. Additionally, proper design and construction practices can also help to limit moments at walls.
The main factors that affect "Restriction of moment at wall" include the design and layout of the structure, the materials used, and the external forces acting on the wall. Other factors such as soil conditions, weather, and seismic activity can also play a role in the amount of moment that a wall may experience.
"Restriction of moment at wall" is closely related to other principles of structural engineering such as load bearing, stability, and strength. By limiting the moments at a wall, the overall stability and strength of a structure can be improved, ensuring its safety and longevity.
