Physics - Mechanical Properties of Solids

Practise 19 BITSAT previous year questions on Mechanical Properties of Solids, compiled from papers spanning 2009 to 2024. Each question is pulled directly from the actual exam paper it appeared in, so you're practising in the exact style and difficulty BITSAT tests.

Mechanical Properties of Solids has been asked in 13 of the 16 years of BITSAT papers analysed (2009–2024), with 19 questions in all. 53% of them were easy, 21% moderate and 26% tough. Most of its questions came from 2024, with 3 questions that year. In the last three years (2022–2024) it had 5 questions across 5 papers, about 1 per paper.

The chapter's 6 topics are not weighted equally: Young's Modulus and Breaking Stres (13 questions, 68%), Young’s Modulus and Breaking Stres (2 questions, 11%), and Elastic Potential Energy (1 question, 5%) have been asked the most. Young's Modulus and Breaking Stres has also led over the last five years, with 3 questions. Young's Modulus and Breaking Stres has produced the most tough questions (2).
