Homework deadline lesson Friday November 29th

As a preparation for Tuesday’s lesson you’ll look into Internal forces and displacement due to torsion:

• Differential equations for equilibrium relations
  • … for torsion
• Solve equilibrium
  • … of a body in torsion
• Solve section forces torsion structures
  • … using equilibrium in a specific cross-section
  • Diagrams
  • … using differential equations
• Model
  • Shear stress-strain diagram
• Cross-sectional properties
  • Polar moment of inertia
  • Torsional moment of inertia thin-walled tubes
• Strain diagram
  • … for torsion
• Kinematic relations
  • … for torsion in circular cross-sections and thin-walled tubes
• Constitutive relations
  • … for torsion
• Solve displacements circular and thin-walled tubes for structures in torsion
  • … using constitutive equation
  • … using differential equations

Please go through the topics which you can improve your skills on. Take at least a look at the examples and try a few exercises. During the lesson you’ll make some advanced exercises.
