Fits in the Universal Testing Machine (SM1000) for double shear tests.

DOUBLE SHEAR

Shear testing determines the shear strength, t, of cylindrical materials. This is based upon DIN50141 standard which is valid for materials with a maximum tensile stregth of 1300 n.mm-2.

The Double Shear Experiment (SM1000j) fits in the area below the loading platform of TecQuipment’s Universal Testing Machine (SM1000).

In a single shear test (one when a specimen is sheared on one cross section), the specimen can bend before it shears, this has to be accounted for to obtain good results with a double shear test, the specimen is sheared at two locations, bending is eliminated resulting in a much simpler test.

The specimen holder fits to the lower ball joint and the shear strap holder to the upper ball joint. The copper specimen is passed through the specimen holder and the shear strap. The two sections are joined by fitting the dowel through the shear strap holder and shear strap. The pump is used to increase the ram force until the specimen shears.

LEARNING OUTCOMES

  • Determining the shear stress of the specimen materials

Compact, bench mounted apparatus enabling a variety of investigations into material stiffness including Young’s modulus.

STIFFNESS – BENDING AND TORSION

A compact, bench-mounting frame that holds different parts for investigations into stiffness of materials. The standard TE16 includes parts for tests in bending of beams of different materials and cross-section. Optional additional kits allow investigations into different beam fixings and torsional stiffness.

The main part is a rigid metal frame. Supplied as standard are two adjustable knife edges that work as simple supports for test beams. A linear scale on the back panel of the frame allows accurate positioning of the knife edges. The kit also includes weights, a magnetic dial gauge and a set of different beams. Also included in the standard TE16 kit is a vernier gauge for students to accurately measure dimensions of the specimens they test.

Students add different loads to the beams using weights on a hanger. The dial gauge indicator on the back panel accurately measures beam deflection.

The Additional Experimentation Kit (TE16a), available as an optional extra, enables further investigations into a simple cantilever, a propped cantilever and an encastre beam. The Additional Torsion Testing Kit (TE16b) is also available as an optional extra. It allows torsion tests on solid rods of different materials and a tube.

LEARNING OUTCOMES

Standard TE16 Kit:

  • Investigation of the stiffness in bending of different materials of the same cross-section (Young’s modulus/stiffness)
  • Investigation of the stiffness of a single material with different cross-section geometries (second moment of area, or I value)

When used with the optional TE16a:

  • Experiments to find the deflected shape of a beam and bending of a beam clamped at one end (a cantilever).
  • Comparison of a simply supported beam, a cantilever and an encastre beam.

When used with the optional TE16b:

  • Experiments to find the relationship between angular deflection and the dimensional and material properties of rods and tubes (torsional stiffness).

HOOKE’S LAW AND SPRING RATE

The Spring Testing Apparatus uses a fundamental variable mass and scale measurement to test springs. It shows students how to find the properties of a spring and proves some basic laws of physics (Hooke’s law, Newton’s law and spring design rules). It is also a useful tool for a workshop, to check the properties of a spring before it is used, or after it has been used.

The apparatus is a compact metal frame with adjustable feet so the user can make the apparatus level. The back of the frame has a storage area for springs and masses. The front of the frame has a metric scale each side of a large slot, where the test spring hangs.

Students choose a spring and note its dimensions. They then slowly load the spring with the masses (included) and note its extension against the metric scale. Students use their results to find the properties of the spring and compare them with theory and the manufacturer’s details. For more advanced studies, students can also do tests on springs in series and parallel.

The user guide (included) gives full details of how to use the equipment, spring theory, experiments and typical results.

Supplied with the apparatus is a set of extension or ‘tension’ springs. The user can compare different spring rates with different spring sizes to fully understand the basic rules of spring design. Tension springs also have the extra ‘initial tension’ that other springs do not have which increases students’ learning about spring properties.

LEARNING OUTCOMES

  • Spring rate and Hooke’s law
  • To prove the basic rules of spring design
  • A simple spring scale
  • Springs in series
  • Springs in parallel
