Tech Tatva’15: It’s Time to Think Mechanical
The Paper Presentations held on October 9th, 2015 started out after a thirty minute delay due to the late arrival of participants. Regardless of the delay, students arrived at the lecture hall eager to present their research. However, to the organizers’ dismay, the projector was not functional and the whole company of students, judges, and organizers had to move to a neighbouring room to begin the presentation. Despite the technical difficulty, the event organizers were pleased to welcome the students. The participants at the event included students from Manipal Institute of Technology, St. Joseph’s Engineering College (Mangalore), and Malnad College of Engineering (Hassan).
The papers being presented were primarily focused on mechanical, automobile, and aeronautical engineering. The first team presented their plans to construct an eco-friendly automobile which runs on an electrical battery. While presenting their papers, each student effectively explained the working of the design and also revealed the vehicle’s drawbacks. Even though the battery powered car eliminated the emission of exhaust gas, the group explained how the car cannot achieve a speed greater than than thirty-five kilometers per hour. The following presentation, by a third-year student from MIT, introduced a new vehicle to vehicle communication system which incorporates the Spread System Technique. This communication system could be used to measure the distance between two vehicles and determine the relative location of the vehicles. Installing it into vehicles would ensure better road-traffic safety.
The next batch of students, from Malnad College of Engineering, presented their idea on improving the speed magnetic levitated trains by reducing friction due to air. The team conducted a unique experiment by building a miniature version of the magnetic levitated train. This construction also helped them in comparing the speeds of the train in a vacuum as opposed to normal room conditions. Two students from St. Joseph’s Engineering College introduced an electrical trigger system for firearms. The team also explained how using an electrical trigger to spark the gunpowder minimizes the recoil and enhances the accuracy of guns.
During the presentations, the judges paid very close attention to the concepts and data presented by the students. They promptly asked questions to verify certain details and ensure that the students’ inferences were credible. The last student to present for the day, introduced a rather astonishing concept of building a kite called ‘Flash’, which would help humans achieve faster speeds while running. It would be interesting to see how the student would go about constructing and testing his idea.
