Unit 102 Mechanics of solids and basic structural
analysis
Assessment Criteria
Outcome 1 Calculate stresses, strain and deflections in simple structural
members under given load conditions
The learner can:
1. Explain the purpose and function of structures, types of structures and describe types of
supports.
2. Identify types of loads and calculate their magnitudes.
3. Use Mohr’s Circle to determine stresses on inclined planes and combined bending torsion and
axial loading.
4. Determine shear force and bending moment, bending stress and shear stress distribution in
beams.
5. Explain Basic Structural Concepts, describe Static Indeterminacy.
6. Determine shear stress and twist of circular solid sections, thin walled sections and simple open
sections.
Range
Stress - a measure of the forces acting on or in a deformable body, measured as the average force
per unit area of a surface on or in the body on which the forces act.
Strain – a measure of the deformation of an element under applied stresses.
Deflection – the displacement of a point on a structure under load
Mohr’s Circle – a two dimensional graphical representation of the state of stress at a point
Static Indeterminacy - static equilibrium equations are insufficient for determining the internal
forces and reactions on a structure and additional methods must be adopted
Outcome 2 Perform elastic analysis of simple structural components
The learner can:
1. Explain and determine Work and Complementary work; Virtual Work; Strain Energy.
2. Describe Basic Energy Theorems.
3. Use virtual forces in obtaining displacements.
4. Use virtual displacements in obtaining equilibrium equations.
5. Apply the principle of minimum potential energy.
6. Use analytical or graphical methods for beam analysis, derive shear force and bending
moment diagrams and deflections for simply supported beams and cantilevers.
7. Analyse statically determinate and statically indeterminate structures by calculating forces for
pin jointed frames, beams, rigid jointed frames and arches.
8. Derive displacements of statically determinate and indeterminate structures; pin jointed frames,
beams, rigid jointed frames and arches.
9. Generate influence lines for statically determinate and indeterminate structures; pin jointed
frames, beams, rigid jointed frames and arches.
Range
Elastic Analysis - examination of structures or materials based on their reaction to stresses in
stretching or bending elastically.
