Mechanical hysteresis
Article No: P2120300
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
