SFD and BMD are graphical representations of shear force and bending moment along a beam.

• SFD (Shear Force Diagram) shows the variation of shear force along the length of the beam.

• BMD (Bending Moment Diagram) shows the variation of bending moment along the length of the beam.

• SFD and BMD are important tools in structural analysis and design.

• They help in determining the maximum shear force and bending moment in a beam, which are crucial for selecting appropriate beam sizes and r...read more

Explaining stiffness matrix of 1D beam element and stress-strain curve in FEM.

• Stiffness matrix of 1D beam element is a 2x2 matrix that relates the nodal displacements to the nodal forces.

• The stress-strain curve in FEM is used to determine the material properties of the beam element.

• The curve is obtained by applying a load to the beam and measuring the resulting strain.

• The slope of the curve is the modulus of elasticity, which is used to calculate the stiffness matrix.

Resonance is the phenomenon of oscillation at a specific frequency. It can be controlled by damping or changing the frequency.

• Resonance occurs when a system is subjected to an external force at its natural frequency.

• It can cause excessive vibrations and damage to the system.

• Resonance can be controlled by adding damping to the system or by changing the frequency of the external force.

• Examples of resonance include a swing, a tuning fork, and a wine glass shattering due to a hig...read more
