Strength of Materials Practice Test Series-I

Description

This practice test is a part of test series of strength of materials. This test series is for all level of learners. It will help you understand your level of understanding of basic knowledge and how to apply it for real life problems. Use it for various types of exams like GATE and IES preparations. Also this test series will be useful in attending viva voce and appearing for job interviews.

It includes various topics of Strength of Materials subject. First being Stresses and Strain which includes topics like types of stresses and strains, derivation for change in length, stress-strain for ductile and brittle materials, elongation of tapered bar, elongation of bar due to self-weight, stress and strain in composite and compound bars, temperature stresses and strains, concept of strain, Poisson's Ratio, uniaxial-biaxial-triaxial loading, elastic constants- and numericals on all these topics.

Second topic being Shear Force Diagram(SFD) and Bending Moment Diagram(BMD). Topics like types of supports, beams, reactions, Shear Force and Bending Moment sign conventions.

Third one is Centre of Gravity(C.G.) and Moment of Inertia(M.I.). Concepts like centroid, centre of gravity, radius of gyration, moment of inertia, polar modulus, section modulus, mass moment of inertia, area moment of inertia, parallel axis theorem and perpendicular axis theorem are included here.

Fourth topic is the concept of Strain Energy. Three cases are included here- gradually applied load, suddenly applied load and suddenly applied load with impact. Strain energy for composite and compound bars is also included.

Fifth topic is Deflection of Beams which includes Flexural formula and Macaulay's method which is then used for solving numericals for calculation of slope and deflection of beams under various loading conditions.

Sixth concept is Theory of Torsion which is about designing shafts and analyzing if the design is safe for practical use.

Seventh concept is Thin Cylinders and Spherical Shells. Concepts like Hoop Stress(circumferential stress) and Longitudinal stress are included here.

Eighth concept is of Columns and Struts which includes Euler's theory and its assumptions for long column, Limitation of Euler's theory and Rakhine-Gordan Formula.

Last one being Bending Stresses in Beams, Shear Stresses in Beams and Direct and Combined Stresses.
