The property of a material by virtue of which it can be beaten or rolled into plates is called a malleability b ductility c plasticity d elasticity e reliability. If a material expands freely due to heating it will develop a thermal stresses b tensile stress c bending d compressive stress e no stress. In a tensile test, near the elastic limit zone, the a tensile strain increases more quickly b tensile strain decreases more quickly c tensile strain increases in proportion to the stress d tensile strain decreases in proportion to the stress e tensile strain remains constant. The stress necessary to initiate yielding is a considerably greater than that necessary to continue it b considerably lesser than that necessary to continue it c greater than that necessary to stop it d lesser than that necessary to stop it e equal to that necessary to stop it. In the tensile test, the phenomenon of slow extension of the material, i. The stress developed in a material at breaking point in extension is called a breaking stress b fracture stress c yield point stress d ultimate tensile stress e proof stress.

Demonstrating the basic principles in the area of strength and mechanics of materials and structural analysis to the undergraduate students through a series of experiments is the objective of the strength of materials lab. Measuring the properties of the materials such as impact strength, tensile strength, compressive strength, hardness, ductility are conducted in the lab. Civil Engineering Objective Types by R. Thin Cylinders For Objective Questions 1. If t is the permissible stress for the cylinder material, then major principal stress h should be less than or equal to t. This laboratory experiment is designed to demonstrate the procedure used for obtaining mechanical properties as modulus of elasticity, yield strength, ultimate tensile strength UTS , toughness, uniform elongation, stress and strain The sign convention for shear force and stress is based on how it shears the materials and this is shown below.

Strength of Materials
When a force is applied to a structural member, that member will develop both stress and strain as a result of the force. The applied force will cause the structural member to deform by some length, in proportion to its stiffness. Strain is the ratio of the deformation to the original length of the part:.
Strain is defined as the ratio of a change in volume to original volume b change in length to original length c change in cross-sectional area to original cross-sectional area d any one of the above e none of the above.

The reason is the electronic devices divert your attention and also cause strains while reading eBooks. The chapter wise segregation has been done to align with contemporary competitive examination pattern. It has been ensured from made easy team to have broad coverage of subjects at chapter level. This Study Materials contains all the formulae and important theoretical aspects of Mechanical Engineering.
Говорит коммандер Тревор Стратмор. У нас в шифровалке человек взят в заложники. Быстро пришлите сюда людей. Да, да, прямо. К тому же у нас вышел из строя генератор. Я требую направить сюда всю энергию из внешних источников. Все системы должны заработать через пять минут.
Танкадо прижал изуродованную руку к груди с выражением недоумения и ужаса на лице. - Вы можете заметить, - продолжал Смит, - что взгляд его устремлен. Он ни разу не посмотрел по сторонам. - Это так важно? - полувопросительно произнес Джабба.
