Physics - Mechanical Properties of Solids

Practise 12 WBJEE previous year questions on Mechanical Properties of Solids, compiled from papers spanning 2009 to 2025. Each question is pulled directly from the actual exam paper it appeared in, so you're practising in the exact style and difficulty WBJEE tests.

Mechanical Properties of Solids has been asked in 12 of the 18 years of WBJEE papers analysed (2009–2026), with 12 questions in all. 50% of them were easy, 42% moderate and 8% tough. Most of its questions came from 2025, with 1 question that year. In the last three years (2024–2026) it had 2 questions across 3 papers, about 0.7 per paper.

The chapter's 4 topics are not weighted equally: Young’s Modulus and Breaking Stres (6 questions, 50%), Bulk Modulus (4 questions, 33%), and Work Done in Stretching a Wire (1 question, 8%) have been asked the most. Young’s Modulus and Breaking Stres has also led over the last five years, with 2 questions. Bulk Modulus has produced the most tough questions (1).
