Determination of Strain in a Steel Bar
Prepare a test specimen of at least 2ft. Measure at least 3 places dia of steel bar by a VC and calculate the average value. Mark the gauge length i.e 2 marks 8” apart.Torsion Test on Mild Steel and Cast Iron - Lab Report
To study the shear stress ~ shear strain behavior of the material. To study the failure pattern of these materials in torsion. To determine the mechanical properties, e.g, Modulus of elasticity, Modulus of rigidity, Shear strength, shear strain and ductility in torsion.Universal Testing Machine and Components of UTM
A machine used to test specimens for tensile strength, compressive strength, shear strength and to perform bend test along other important laboratory tests. The primary use of the testing machine is to create the stress strain diagram. Once the diagram is generated, a pencil and straight edge or computer algorithm can be used to calculate yield strength,Tensile Strength or Tension Test
Tensile strength of a material is the tension stress at which a material breaks or permanently deforms (changes shape) Toughness, Resilience, Poisson's ratio can also be found by the use of this testing technique. This data is plotted as load vs elongation and then converted to engineering stress (load/original area) vs engineering strain (fractional change in length overTo Find out the Reaction of Simply Supported Beam
Condition of equilibrium for vertical parallel forces acting on a body is Sum of all the force s should be zero. It should satisfy the principle of moments . If we take moment about a point on moments should be equal to anti clockwise moments.
