Deformation of curved-axis beams
Principle of virtual forces for calculating deformation
Features
- elastic deformation of curved-axis beams
- circular, semi-circular and quadrant beams
Learning objectives/experiments
- bending behaviour of a curved-axis beam
-- circular beam
-- semi-circular beam
-- quadrant beam
- application of the principle of virtual forces (the force method) to calculate deformation
- second moment of area
- comparison of calculated and measured deformations
