## AboutStrength of Materials - SOM

Free Strength of Material app is a complete handbook with diagrams and graphs. It is part of Mechanical engineering education which brings important topics, notes on the subject. The App serves as a quick reference guide on mechanical engineering subject.

this app often refers to various methods of calculating the stresses and strains in structural members, such as beams, columns, and shafts.

It covers 157 topics of strength of materials in detail. These 157 topics are divided into 5 units and you can find all the basics of strength of materials in the app. You can make important notes of strength of materials nptel for exam preparation.

This App is extremely helpful as quick learning guide on your mobile at the time of exams, jobs interviews, test prep & training. You can track your learning, set reminders, edit the study material, add favorite topics, share the topics on social media.

The App covers the topic in a flashcard-like format, the purpose of the App is faster learning and revisions of the subject. You can consider this App as notes which professors guide in a classroom.

You can very easily pass and succeed in your exams if you have this App on your mobile phone, and give an overview just a few days.
