Equipment                         

Application

Timber Testing Machine

Testing of timber for compressive strength, flexural strength, shear strength

and impact strength

Tensometer ( Capacity - 2 Tons)

Tensile testing of standard circular specimens, flat plates and wires

Bending moment apparatus

This experimental apparatus provides visualization and proof of the basic

theory of bending moments in a beam. Using this apparatus, students can

investigate the variation of bending moment at a point away from the point

of loading of a simply supported beam.

Shear force apparatus

This experimental apparatus provides visualization and proof of the basic theory

of shear forces in a beam. Using this apparatus, students can investigate the

variation of shear force at a point away from the point of loading of a simply

supported beam.

Biaxial bending

An experimental apparatus to allow students to investigate the difference

between axis of bending and axis of bending moment when the applied moment

is about a non-principal axis of the section.

Shear centre apparatus

An experimental apparatus for determining the shear centre of a cross-section

of a given specimen 

Pin jointed framework

An experimental apparatus to allow students to create a wide selection of

pin-jointed frameworks and then investigate the effects resulting from applying

loading forces to them.

 Shear force apparatus

An experimental apparatus to allow students to investigate the variation of

shear force on a supported specimen

Torsion apparatus

An experimental apparatus to allow students to investigate the relationship

between torque and twist in the elastic region of solid circular sections in

various materials.

Buckling of struts apparatus

An experimental apparatus to allow students to investigate the deflection

and stability of struts under various end conditions.
