b. To determine the stiffness of the test spring (s).

2. Extension of a spring

a. To obtain the relationship between the forces applied to an extension spring and its change in length.

b. To determine the stiffness of the test spring (s).

3. Rubber in Shear

a. To determine the variation of deflection with applied load.

b. To investigate how shear strain varies with shear stress.

c. To determine the Modulus of Rigidity of the rubber block.

4. Hooke’s Law for Wires

a. To determine the Young's Modulus of Elasticity of the specimen wire. b. To verify Hooke's Law by experiment.

5. Strain in Compound Wires

a. To determine the modulus of elasticity of two wires and hence evaluate the equivalent Young’s Modulus of Elasticity of the combination b. To position the single applied load on the slotted link in order that both wires are subjected to common strain and hence to establish the load in each wire
