The force measuring arrangement is notable in that the second fastening device has a magnet (37) that is designed to retain the force transmission element (27) at least in a state connected to the second force absorption region (51) in a force-transmitting manner.

A method for testing for hydrogen embrittlement, including mounting a container around a steel alloy test specimen, the container having a closed bottom below a notched area on the test specimen and an open upper end above the notched area; applying a tensile load to the test specimen and sustaining the load for a selected duration to incubate potential hydrogen embrittlement cracks with a sub-critical flaw size if sufficient hydrogen in dangerous levels is present in the test specimen; then, while sustaining the load, dispensing a cryogenic fluid into the container, immersing and chilling the notched area, reducing the sub-critical flaw size for any hydrogen embrittlement cracks incubated; and with the sustained load, fracturing the notched area if the sub-critical flaw size of any hydrogen embrittlement cracks incubated reaches a critical flaw size.

The present application provides a testing device. The testing device includes: a box, a pressing mechanism, a sliding mechanism, a transmission mechanism, and first clamping mechanisms. The pressing mechanism is located inside the box. A gap between the pressing mechanism and the first side of the box is used to place substrates to be tested. The pressing mechanism is slidably connected to the sliding mechanism. The transmission mechanism is connected to the pressing mechanism to drive the pressing mechanism to move. Each first clamping mechanism is used to hold one of the substrates to be tested.

The invention relates generally to a mechanical device that efficiently measures physical parameters such as compression strength, elasticity, firmness, deformation resistance and the like, on one or a plurality of compressible test objects including fruits, nuts and vegetables, and which operates in a semi-automatic fashion using a rotatable turntable with multiple wells to hold a plurality of test objects in place during measurement using one or more positionable sensors capable of measuring a physical parameter when brought into contact with the test object.
