The utility model discloses a when counter -bending experimental apparatus of different cross -section roof beams of area relates to material mechanics experiment equipment field, through quantitativedetermination can audio -visual comparison etc. The counter -bending ability of the different shape cross -section roof beams of cross sectional area, strengthen experiment teaching effects. The utility model discloses a: test piece, locating plate, support rigid frame, constant head tank, support, loading system, force cell sensor, loading pressure head, power display instrument, amesdial and support. The loading pressure head pushes down, and the deformation weight amount of deflection of test piece reachs through the amesdial measurement, and bending strain measures through the resistancestrain gauge constitution measuring bridge who pastes on the test piece, and the corner is through reaching with the amount of deflection relational expression is indirect. The utility model disclosesa ration test leaves deep
