This module provides students with the necessary knowledge of mechanical stress and strain theory which when applied allows them to design mechanical components and/or structures capable of withstanding a required load. The module then studies the implementation of these designs by examining the components required to convert the designs into real world systems.

Direct stress and strain. Stress and strain in compound bars. Buckling. Thermal stress. Shear stress. Torsion. Shear force diagrams. Bending moment diagrams. Bending stress. Stress concentration. Fatigue. Prime movers. Belt drives. Gears and gear trains. Bearings. Shafts and couplings.

On successful completion of this module, students should be able to: - State and define the types of stress and strain that apply to components under loading conditions. - Analyse tensile and compressive stresses in bars subject to axial loads, thermal stresses in bars subjected to an increase in temperature, shear stresses in circular bars subject to a torque and bending stresses in beams subject to transverse loads - Draw shear force and bending moment diagrams for beams under point loads. - Explain fatigue and stress concentration theory in terms of component failure. - Use the factor of safety theory in order to design for components under load. - Describe the operation of prime movers such as the four stroke engine, dc motor, stepper motor and hydraulic motor. - Describe the operation of gears and gear trains and differentiate between the different types of gears. - Describe the operation of belt drives and apply the necessary theory to design for strength requirements. - Explain the function of bearings, shafts and couplings in mechanical systems.
