SD-3.11 – Unsymmetrical Cantilever Apparatus
The Unsymmetrical Cantilever Apparatus is intended to demonstrate the unsymmetrical bending of beams.
The Unsymmetrical Cantilever Apparatus is intended to demonstrate the unsymmetrical bending of beams. Simple experiments may be carried out to determine the deflections Δu and Δv at the free end of cantilevers of various sections for varying angles of applied load from which the relationship between Δu/W and Δv/W may be determined graphically.
The apparatus consists of 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 15° intervals through 180°. 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 Δu and Δv deflections of the beam are measured by means of two dial gauges mounted at 90° to each other on the head. To compensate for any lateral deflection of the beam, the line of action of the applied load can be adjusted by lateral adjustment of the load pulley.
The apparatus is portable and is intended for bench mounting, requiring no fixing.
The basic apparatus is supplied with a cantilever specimen of 12 x 12 x 3 equal angle section bright mild steel.
Other specimens are available to special order (in brass):
Channel (16 x 16 x 1.6 x 240mm long);
Angle (16 x 16 x 1.6 x 240mm long);
Semi-circular (22mm Ø diameter, 19mm Ø bore tube x 240mm long);
Zed section (19 x 19 x 1.6 x 240mm long).
