circle shaped bars under static load
Technical description
The unit enables the deformation of lightly curved bars under load to be meas-
ured. One after the other, a circular bar, a semicircular bar and a quarter circle
shaped bar made of metal can be loaded using varying weights. Displacement
dial gauges record the transverse and longitudinal deformation. To make the
measurements comparable and to simplify the calculation, all three bars are of
the same cross-section and thus have the same geometrical moment of inertia.
Suction feet ensure that the unit does not slip. Due to its strong construction,
the unit is extremely well suited to student experiments.

WP 120 BUCKLING TESTER
Technical description
All components subject to pressure are at risk
from buckling. There is thus a wide practical
basis for this tester. The tester consists of the
base frame, guide columns and load cross-
member. The base frame contains the lower
bearing for the test bar. This comprises the test
load sensor and a changeable receptacle for two
different pressure pads, depending on the bear-
ing conditions. Due to the height adjustable load
cross-member, test bars of varying buckling
lengths can be investigated. A hand operated
load spindle is used to generate the test force.
An axial bearing between the spindle and the
pressure pad prevents torsional loading of the
test bar. Using the shear loading device, it is
also possible to generate a defined shear force
on the bar. The unit can be operated positioned
vertically or horizontally, for this purpose the
load gauge can be rotated 90°.

WP 130 COMBINED BENDING AND TORSION APPARATUS
Technical description
This test unit enables various equivalent stress
hypotheses from materials science to be
checked experimentally. Specimens made of
different metals can be placed in a state of stress
in several axes. A circular shaped load plate is
used as a lever for the load moment, loading is
applied by attaching weights to the circumfer-
ence of the plate. The specimen is clamped in
the centre of the plate using clamping levers. Via
the defined points for the application of force,
combined bending and torsion loading is gener-
ated. The angular position of the load weight can
be moved in 15° steps. The deformation is
measured diametrically opposite the points
where the force is applied, that is at the point of
maximum deflection. In this way the measure-
ment error due to the deformation under load of
the test apparatus is minimised. Compensation
for the dead weight of the plate and compensa-
tion for the load weight ensure specimen loading
is free of transverse forces.
Experiments
• Multiple loading of metal specimens using
combined torsion and bending
- Determination of the yield point
- Checking the direct stress hypothesis
- Checking the shear stress hypothesis
• Loading of the probes with pure bending or pure torsion, or
a combination of both
• Transverse force-free specimen loading through suitable
methods of compensation
• Simple, clear layout
• Uses plain, low cost specimens
