Introduction to internal forces

This engineering statics tutorial introduces internal forces in members. The internal forces that we look at here are axial force, shear force, and internal bending moment. If you “virtually cut” a member and remove one side, the part that remains must still be in static equilibrium. It’s the internal forces that are transferred across the virtual cut that keep each side in static equilibrium.
