i did a test about bending moment and shear force(material lab), but i don't understand how does the equipment works..? what kind of sensor do the machine use?

a dimension change act as sensing element ;this change help to change of resistance when it is conected to an electrical ckt with sup[ply voltage &change of resistance creat change in voltage this change in voltage is futher processed & and finally at display screen give results; it also can be done by LVDT in which again displacement is converted to displace ment of a core( solid metalicplate type str)movable in atranse former in between primary & secondry with equalnomber of windings;with the position of core out putvoltage changing;

I don't know the particular machine involved, but most machines of that type use either a pressure gauge (possibly hydraulic) or a force gauge to show the applied stress.

pressure sensor (relif valve ) like on power steering in car
