Underwater Prerna rudder free vibration in the Department of Mechanical Engineering, Indian Institute of Technology, Kharagpur. Courtsey : Prof. Amiya K. Mohanty, Lab-in-charge. Project Investigator : Mr. Ameya Kannamwar, Co-investigator : Mr. Rahul Jindal, Impact-generator : Mr. Yogesh Verma; Photographer + data recorder (referee) : Mr. Prateek Sinha.
Paper accepted at http://www.asmeconferences.org/OMAE2015/, "Free dry and wet vibration of 2-way tapered hollow marine rudder with non-classical pivot : theoretical study", based on Mr. Rahul Jindal's Autumn 2014 BTP (B.Tech Project) work.
Paper accepted at 22nd International Congress on Sound and Vibration (ICSV22), Florence, Italy, 12-16 July 2015 : N. Datta and R. Jindal, “Wake-induced
flutter of 2-way tapered hollow stiffened marine spade rudder in non-uniform
propeller slipstream”, 22nd International Congress on Sound and Vibration (ICSV22), Florence, Italy, from 12 to 16 July 2015; based on Mr. Rahul Jindal's Spring 2015 BTP work.
In IIT-JEE 2001, I made a terrible mistake in Problem # 13 (volume flux, involving differential equations and trigonometric integration, http://www.askiitians.com/iit-papers/iit-jee-2001-mathematics-mains.aspx) in the Mathematics paper (Main examination). This 10-marks problem slid my All India Rank by, say, 300-350.Today, after 14 years, I extracted that paper; and without any preparation, re-solved that problem correctly in 10 min. (Verified with FIITJEE solutions). Another neuron of self-confidence added!
