Theory
Background:
1.
Strain Gauge
This
apparatus is used to measure the amount of strain produced and its
distribution when force is applied on the specimen. It has a
significant importance in the stress strain analysis.
The
experiments related to tensile stress, torsion and bending are
performed on this apparatus.
2.
Torsion of bars apparatus
This
apparatus is used for measuring the strength of bars, and distortion
in bars which is resulted due to a twist.
3.
Extension spring apparatus
This
apparatus is used to measure the actual stiffness of a spring
4.
Compression spring apparatus
This
apparatus is used to measure the actual stiffness of a spring
5.
Rubber in shear apparatus
This
apparatus is used for determining the shear stress, shear strain and
modulus of rigidity of rubber
6.
Universal Testing Machine:
This
apparatus is used to measure the yield strength, tensile stress and
bending e.t.c in materials, when they are subjected to loads and
stresses.
