Required practical 18: force and extension

Key ideas1 of 3

Measure the original length

Clamp a spring securely beside a vertical ruler. Measure its original length before loading, using a pointer and reading at eye level to reduce parallax. Add known loads in small steps. Wait for oscillations to settle before each reading. Calculate force from each load’s weight using the given g.

Spring extension apparatus includes a weighted clamp stand, fixed ruler A, spring B, mass hanger C, pointer and safety tray.
