SBC stands for Safe Bearing Capacity in civil engineering design.

• SBC stands for Safe Bearing Capacity in civil engineering design.

• It is the maximum pressure that can be applied to the soil without risking shear failure.

• SBC is an important parameter used in foundation design to ensure the stability and safety of structures.

• For example, if the SBC of a particular soil is 200 kN/m^2, it means that the maximum pressure that can be applied to that soil is 200 kN per square meter.

Bending moment diagram shows variation of bending moment along the length of a simply supported beam.

• Bending moment is zero at the supports and maximum at the center of the beam.

• The diagram is typically parabolic for a uniformly distributed load.

• For point loads, the diagram consists of straight lines connecting the points of load application.

• Calculations involve determining reactions at supports and applying equilibrium equations.
