Bending Test on Wooden Beam
The objective of bending test on a wooden beam is to study the bending or flexural behavior of the wooden beam and to determine the Modulus of Elasticity and Modulus of Rupture of the wood. Equipment Required 10 ton Buckton ...
Brinell Hardness Test for Metals
The Brinell hardness test is an optical testing method for samples with coarse or inhomogeneous grain structure. This is the best test method for achieving the bulk or macro-hardness of a material, particularly those materials with heterogeneous structures. The difference ...

EQUIPMENT REQUIRED Clerk-Maxwell’s reciprocal’ theorem apparatus Tire weight Dial gauge THE THEOREM Clerk-Maxwell’s reciprocal theorem state that in a linearly elastic structure, ...
Spring Material Test (Modulus of Rigidity)
Modulus of rigidity is the measurement of the stiffness of spring material or its elastic ability. The modulus of rigidity of a spring material varies as a function of chemical composition, cold working, and degree of aging. Apparatus Required Spring ...
Torsion Pendulum Test on Metal Wire
Modulus of Rigidity is the coefficient of elasticity of wire for a shearing force. In simple words, rigidity modulus of a metal wire is a measurement of the capability of a material to resist deformation when external tangential (parallel to the surface) force ...
