摘要:
A mechanical component (100) for a motor vehicle has a test region (102) and a deformation element (104) mechanically coupled to the test region (102). When the mechanical component (100) is in operation and is subject to a stress load, the test region (102) undergoes deformation. The deformation element (104) is configured to respond to the deformation of the test region (102) by undergoing deformation which is greater than that experienced by the test region (102) and which can be detected by a magnetic field sensor (120, 122).
