    Construction and working of UTM The universal testing machine has two vertical threaded shafts. The Crosshead will be constant. These two heads will have locking clamps to hold the specimen in place. If it is a tensile test then the specimen will be placed in between the Cross head and the movable head jaws. If it is a compressive test The specimen will be placed in between the movable head and the table. There is a speed controller, this controls the speed of the two vertical threaded shafts, as the result, there will be a change in the load applied to the specimen with the help of the movable crosshead. With the help of the loading dial indicator, we can observe how much load is applied to the specimen during the test. We can do both the Tensile test and the compressive test on this universal testing machine. Not only these tests there are some other tests such as the flex test. Conclusion We have discussed how UTM is constructed and the working principle for both the tensile test and the compression test. If you have any thoughts please leave them in the comments section below.

    Ensure that there is a small gap within crossheads and the specimen. After selecting suitable range on load dial gauge close the release valve and slowly open the control valve.

    Note the readings of load at three different instants. Apply the load till failure of the specimen takes place, this is the maximum load or failure load generally denoted by P.
