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. The set is manufactured by Science Lab Supplies on its Saha, Ambala premises, Plot 448, HSIIDC Industrial Area, India, and schools, colleges, tender contractors and distributors buy it directly from the producer.
Specifications
Stand, springs, masses and measuring tools of the Hooke's law set occupy one row each in the table. In short, spiral springs of 32.5 x 13.5 mm hang from a 700 mm tripod stand with a 10 mm rod and quadrangular base, are loaded with ten metal masses of 10–50 g, and are measured with a 1.5–2 m meter strip and a digital stopwatch.

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. As a Hooke's law spring kit in India, it suits Class 11 and 12 physics practicals and first-year college 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, with larger loads available from the Mass Set with Hangers.
- 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, set beside the graduated scale of the ESAL Mechanical Spring Balance.
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. Extra springs or masses can be 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. Spring-constant sets for your practical groups can be priced after you write in on the contact page or add them to the enquiry cart; the lab tender page covers institutional bids.
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?
Hooke's law sets of this pattern are made at the company's factory in Saha, Ambala, India; Science Lab Supplies is therefore the manufacturer, and buyers deal with it 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 so the quotation can reflect them.
