Research Challenges

Every challenge starts with a real JEE problem — then unravels it: break the textbook's assumptions, collect your own evidence, design under real constraints, and defend what you found.

⚙️ Mechanics

The safest speed on an Indian road

A motorcycle takes a banked curve. Go too fast and it slides outward; the road banking and friction together decide the safe range.

⚙️ Mechanics

A speed breaker that slows vehicles without hurting passengers

A vehicle crossing a speed breaker can go airborne if it's going too fast for the bump's curvature.

🔥 Thermodynamics

Designing a leak-detecting water tank

A tank drains through a small hole at a rate that depends on the water height above it — the height-vs-time curve has a very specific predicted shape.

🔥 Thermodynamics

Why does a matka cool water?

An unglazed clay pot keeps water cooler than the surrounding air, with no electricity at all.

🌊 Waves & Oscillations

Mapping noise around schools

Multiple traffic noise sources combine at a classroom window, and the combined loudness isn't simply additive in decibels.

⚡ Electrostatics

Designing a low-cost indoor air-quality indicator

A cheap gas sensor changes its electrical resistance depending on pollution level, and that change can be read out as a voltage.

🔦 Optics

A phone-based microscope for village schools

A cheap extra lens held in front of a phone camera can turn it into a usable microscope.

⚙️ Mechanics

Finding the best angle for rooftop solar panels

A solar panel receives less power when sunlight hits it at an angle, even at the same light intensity.
