Details of Learning Activities
Teacher-led :
• Demonstrate use of the interactive PowerPoint presentations re. bending moments (see Resources)
• Overview of bending theory of beams, construction of shear/bending moment diagrams and sample calculation of stress and deflection.
• Review notes and sample calculations in the course text relating to the manipulation of coplanar force systems
• Demonstrate the calculation process for support reactions using point loads and UDLs
• Illustrate selection of member sizes using Manufacturer’s charts and first principles
• Relate stress, strain and Young’s Modulus and hence determine axial deformation. Illustrate stress/strain curves for common materials used in the workplace.
• Review sample calculations in the course text on reaction forces for beams and cantilevers
• Explain the relevance of section properties in the design process using examples from industry
Student-based problem-solving :
Participate in individual problem solving activities completed to industry standard related to typical engineering workplace problems requiring:
• Solution of stress and deflection involving point loads and UDLs
• Determination of reactions for simply-supported and cantilever beams using point loads and UDLs
• Sizing of members subjected to normal, shear and bearing stress
• Calculation of section properties for symmetrical and non-symmetrical beams and compare with Manufacturer’s charts
• Combination and resolution of concurrent and non-concurrent coplanar force systems and application to workplace situations
• Determination of bending stress using beam properties from OneSteel charts and from first principles
Group activities
Working in pairs on a computer, students will develop responses to questions, and consider responses, in the PowerPoint presentations.
