Engineering paraprofessionals are often required to assist with the design of structures (machines, beams, columns, trusses etc) to support or transmit forces and moments. Invariably the conflicting requirements of adequate safety and acceptable economy must be satisfied. This can only be achieved by a thorough appreciation of the principles involved. Accordingly this unit presents the fundamentals of statics of real bodies and strength of materials, by a coverage of the following topics: forces and moments; force systems; resultants of force systems; equilibrium of real bodies; forces in trusses; simple (static) friction; properties of cross sections (centroids, second moments of area, radii of gyration); stress, strain and elasticity; axial force, shear force and bending moment diagrams; flexural stresses; inelastic bending; introduction to design methods.
