MVV. Unsymmetrical Cantilever Unit
SPECIFICATIONS SUMMARY
PRACTICAL POSSIBILITIES
This unit is intended to demonstrate the unsymmetrical bending of beams.
Simple experiments may be carried out to determine the deflections Duand
Dv at the free end of cantilevers of various sections for varying angles of
applied load from which the relationship between Du and Dv, may be

determined graphically.
The unit consists os a vertical cantilever rigidly clamped at its lower end to
the main column which is attached to a rigid base. Beams of varying
sections may be used. A loading head, located at the upper end of the
column, can rotate freely about the vertical axis of the beam and a locating
pin enables the head to be locked at 15º intervals through 180º. A
horizontal load may be applied to the free end of the beam by means of a
cord attached to the beam and passing over a pulley mounted on the
rotating head. The Du and Dv deflections of the beam are measured by
means of two dial gauges mounted at 90º to each other on the head. To
compensate for any lateral deflection of the beam, the line of action of he
applied load can be adjustable by lateral adjustment of the load pulley.

a co-planar rotating system can be
simulated and the normal methods
used.
4.- Oscillation set up by any
unbalanced force may be observed.

MBU. Universal Bench Mounted Frame
SPECIFICATIONS SUMMARY
PRACTICAL POSSIBILITIES
The frame is designed to accommodate two units, allowing adequate space
for students to work on each piece of equipment simultaneously.
However it is possible to mount three pieces, in the case of the simple
transmission system.
Dimensions (approx.): 700 x 1200 x 50 mm. Weight: 30Kg.

MCD. Thin Cylinder Unit
SPECIFICATIONS SUMMARY
Thin Cylinder Unit permits the investigation of stresses and strains in a thin
cylinder under internal pressure.
The thin walled alloy cylinder, supported by a cradle is mounted on a base
board together with the hydraulic hand pump for pressuring the system.
Two stress conditions are available:
- Open ends - circumferential stress.
- Closed ends - bi-axial stress.
The cradle is designed to quickly allow the selection of either condition.
Six strain gauges are fitted to the cylinder to allow the measurement of
surface strains at various angles.
A pressure gauge indicates the cylinder pressure.
PRACTICAL POSSIBILITIES
Some practical possibilities:
1.- Investigation of stresses and strains
in a thin cylinder under internal
pressure.
2.- Two stress conditions are available:
-Open ends -circumferential stress.
-Closed ends -bi-axial stress.
3.- Measurement of surface strains at
various angles.
4.- May be observed the cylinder
pressure.
