Mechanical hysteresis Principle The relationship between torque and angle of rotation is determined when metal bars are twisted. The hysteresis curve is recorded. Benefits - Beyond Hooke's law
- Hysteresis – mostly known from the field of magnetism – can be experienced in mechanics
- Learn the meaning of the words stress, relaxation and equilibrium in a physics context
- Various torsion rods out of different material and with several diameters included
Tasks - Record the hysteresis curve of steel and copper rods.
- Record the stress-relaxation curve with various relaxation times of different materials.
Learning objectives - Mechanical hysteresis
- Elasticity
- Plasticity
- Relaxation
- Torsion modulus
- Plastic flow
- Torque
- Hooke's law
