7/3 Simply Supported Beams - Objectives

Explain the principle of loading in relation to simply supported beams.

• The principle of loading in simply supported beams involves the distribution of loads along the beam's length, affecting its bending and shear forces.

• The principle of loading in simply supported beams is about the beam's ability to support axial loads without bending.

• The principle of loading in simply supported beams refers to the beam's capacity to resist torsional forces.

• The principle of loading in simply supported beams is related to the beam's thermal expansion properties.

Explain the principle of reaction forces in relation to simply supported beams.

• Reaction forces in simply supported beams are the forces that develop at the supports to maintain equilibrium.

• Reaction forces in simply supported beams are the forces that develop at the midpoint to maintain equilibrium.

• Reaction forces in simply supported beams are the forces that develop along the entire length to maintain equilibrium.

• Reaction forces in simply supported beams are the forces that develop at the ends to maintain equilibrium.

Explain the principle of loaded components in relation to simply supported beams.

• Loaded components in simply supported beams are the parts of the beam that carry the load.

• Loaded components in simply supported beams are the parts of the beam that do not carry any load.

• Loaded components in simply supported beams are the parts of the beam that are decorative.

• Loaded components in simply supported beams are the parts of the beam that are optional.

Explain the principle of shear force in relation to simply supported beams.

• Shear force is the internal force parallel to the cross-section of the beam.

• Shear force is the external force perpendicular to the cross-section of the beam.

• Shear force is the internal force perpendicular to the cross-section of the beam.

• Shear force is the external force parallel to the cross-section of the beam.

Explain the principle of load distribution in relation to simply supported beams.

• Load is distributed evenly across the beam.

• Load is concentrated at the center of the beam.

• Load is only applied at the supports.

• Load is distributed unevenly across the beam.

The principle of bending moments in relation to simply supported beams is explained by:

• The distribution of forces along the beam
