Apparatus for Demonstrating Hooke's law (Determination of Elasticity Constant)
Product Code : SCL-PL-11805
Apparatus for Demonstrating Hooke's law (Determination of Elasticity Constant) (SKU SCL-PL-11805) is a spring-loading set for finding the spring constant k from the extension produced by known masses. It serves Class 11 practicals on elasticity and introductory mechanics labs in colleges and polytechnics. Science Lab Supplies makes this apparatus in-house at Plot 448, HSIIDC Industrial Area, Saha, Ambala, India, and supplies it straight to schools, colleges, tender contractors and distributors.
Specifications
The springs hang from a tripod stand with a vertical metal base, a 10 mm diameter rod, a quadrangular base and a height of 700 mm. Spiral springs measuring 32.5 x 13.5 mm (length x diameter) are loaded with ten metal masses of 10–50 g, and extensions are read with a 1.5–2 m meter strip.

Applications and Experiments for the Hooke's Law Apparatus
The apparatus verifies that extension is proportional to load within the elastic limit and gives the spring constant from the slope of a load–extension graph. It is a standard entry on the physics lab equipment list for Class 11 and 12 and in first-year mechanics labs.
- NCERT Class 11 physics (Mechanical Properties of Solids): Hooke's law and the elastic limit.
- Class 11 practical: plotting load against extension to find the spring constant k.
- Class 11 Oscillations: timing a loaded spring with the stopwatch and comparing k from T = 2π√(m/k).
- Polytechnic and first-year college mechanics: elasticity and stiffness of springs.
Standard Scope of Supply
Each set includes the tripod stand with vertical metal base and quadrangular base, the insulating-head rod, spiral springs of 32.5 x 13.5 mm, a box of ten metal masses from 10 g to 50 g, a 1.5–2 m meter strip and a digital stopwatch. Extras requested are itemised on the quotation.
Packing, MOQ and Lead Time
Whether you need one demonstration set or one for each practical group, the quotation lists packing, delivery time and price for the quantity requested. Additional mechanics lab equipment in India from the same range can be included on it.
Science Lab Supplies, which holds an Importer-Exporter Code, can ship to buyers in Rwanda, South Africa, Qatar, Sri Lanka, Vietnam and Malaysia. Send your requirement via the contact page, collect items in the enquiry cart, or refer to the lab tender page for institutional tenders.
Frequently Asked Questions
How is the spring constant found with this apparatus?
Hang masses from 10 g to 50 g on the spring, record each extension on the meter strip, and plot load against extension; the slope gives the spring constant k.
Why is a stopwatch included?
The digital stopwatch lets students time oscillations of a loaded spring, giving a second way to estimate the spring constant and linking Hooke's law to simple harmonic motion.
Is Science Lab Supplies the manufacturer or a trader?
Science Lab Supplies is the maker. The set is produced at its factory in Saha, Ambala, India, and buyers deal with the manufacturer directly from enquiry to dispatch.
What size are the springs?
The spiral springs measure 32.5 x 13.5 mm, length by diameter. For other spring sizes, please ask through the contact page before ordering.
Related Elasticity and Force Apparatus
Hooke's law connects springs, force measurement and oscillations, so these four Physics Lab items sit well beside this set. They extend the same practical sequence from spring balances to pendulums and turning forces, and can be added to the same quotation.
- Spring Unit — a clock-spring energy-transfer unit for converting stored spring energy into electrical or kinetic energy.
- Set of Dynamometers — spring balances in grams and newtons, 2.5 N to 50 N.
- Mathematical Pendulum Demonstration Apparatus — oscillation studies alongside spring timing.
- Apparatus for Demonstrating the Moment of Force — uses the same 10–50 g mass range for turning forces.
