Strength of materials – i Course Objectives

To impart preliminary concepts of Strength of Material and Principles of Elasticity and Plasticity Stress conditions and to develop diagrams of variation of various stresses across the length.

To give concepts of stresses developed in the cross section and bending equations calculation of section modulus of sections with different cross sections

The concepts above will be utilized in measuring deflections in beams under various loading and support conditions

To classify cylinders based on their thickness and to derive equations for measurement of stresses across the cross section when subjected to external pressure.

Strength of materials – i Course Outcomes

The student will be able to understand the basic materials behavior under the influence of different external loading conditions and the support conditions

The student will be able to draw the diagrams indicating the variation of the key performance features like bending moment and shear forces

The student will have knowledge of bending concepts and calculation of section modulus and for determination of stresses developed in the beams and deflections due to various loading conditions

The student will be able to assess stresses across section of the thin and thick cylinders to arrive at optimum sections to withstand the internal pressure using Lame’s equation.
