After completing this experiment, you will be able to:

• Understand the behaviour of a close-coiled helical compression spring under axial loading.
• Measure the compression (deflection) produced for different applied loads.
• Determine the stiffness (spring constant) of the spring.
• Calculate the strain energy stored in the spring during elastic deformation.
• Plot the Load–Deflection graph and interpret its significance.
• Verify Hooke's law for a helical compression spring within the elastic range.
• Relate spring characteristics to practical engineering applications.
