what is universal testing machine
A universal testing machine (UTM), also known as a universal tester,[1] materials testing machine or materials test frame, is used to test the tensile strength and compressive strength of materials. An earlier name for a tensile testing machine is a tensometer. The "universal" part of the name reflects that it can perform many standard tensile and compression tests on materials, components, and structures (in other words, that it is versatile).

How does a universal test machine work?
A Universal testing machine (UTM) is used to test the mechanical properties (tension, compression etc.) of a given test specimen by exerting tensile, compressive or transverse stresses. The machine has been named so because of the wide range of tests it can perform over different kind of materials.

Why UTM is called universal testing?
A Universal Testing Machine (UTM) is used to test both the tensile and compressive strength of materials. Universal Testing Machines are named as such because they can perform many different varieties of tests on an equally diverse range of materials, components, and structures.

Who invented universal testing machine?
Tinius Olsen
From the 1850's on, various devices for testing materials had been developed, but the goal of a truly universal testing machine proved elusive until 1880, when Philadelphia engineer Tinius Olsen, a Norwegian immigrant who had just lost his job, devised and patented what became known as the Little Giant.

What does a tensile test tell you?
Tensile testing is a destructive test process that provides information about the tensile strength, yield strength, and ductility of the metallic material. It measures the force required to break a composite or plastic specimen and the extent to which the specimen stretches or elongates to that breaking point
What is gauge length in UTM?
The term 'gauge length' refers to the part of a test specimen actually being measured for elongation during a tensile test. ... In this case, the term refers to the original length of a specimen before the test starts.

What is capacity of UTM?
Single-column UTM machines are lower force machines and lower cost. They come in frame capacities up to 1000 lbf. ... UTMs can be outfitted with interchangeable load cells They are typically available from as little as 1lb capacity and will range up the machine's maximum capacity.

Which test can be performed on UTM?
A universal testing machine (UTM), also known as a universal tester, materials testing machine or materials test frame, is used to test the tensile strength and compressive strength of materials

How do you calculate tensile strength in UTM?
Actual Breaking Stress = Breaking load/Neck Area. Percentage elongation = (Change in length/Original Length)/100. Percentage reduction in the area = (Change in length/Original Area)/100.

How do you test tensile strength at home?
Procedure
Tie a short length of your test material in a secure knot around the hook of the spring scale.
Secure the top of the spring scale to something steady, like a table or wall.
Pull on the test material until it breaks. ...
Record the force measured by the spring scale right before the test material breaks.
