Student Opinion[edit | edit source]

An easy subject where you can secure high grades with little practise and good understanding of concepts. Generally good professors are assigned in this course, so they explain you much nicely that the only thing you need to do back in hostel is solve a selected number of problems and the Previous Year Papers. If thats not the case with you I would recommend you to watch JEFF HANSON videos on Youtube: https://www.youtube.com/user/1234jhanson

Be ready for step marking, so even if your answer is wrong you get credits for your procedure.

And do solve problems from books: Merriem Kraige Statics http://aghababaie.usc.ac.ir/files/1506464236211.pdf and Beer Johnston Material MEchanics: http://www.hljp.edu.cn/attachment/20120820084627006.pdf and Statics : https://mechzoneblog.files.wordpress.com/2017/08/statics-and-mechanics-of-materials.pdf
