Course on Shear Stresses in Beams. Shear stresses in beams can be caused by either applied loads or wind loads. In the case of applied loads, shear stresses may be induced in the beam by forces applied at one or more points along the beam. For example, shear stresses may be induced when a weight is hung from a beam’s end. In the case of wind loads, shear stresses may be induced when the wind blows against a beam’s surface.

Shear stress is defined as the stress that exists due to the displacement of one structural element relative to another. Shear stress can arise in any material when there is a mismatch between its elastic properties and its plastic properties. In beams, shear stress is typically highest near the points where loading occurs (i.e., at joints and along edges).

There are two ways to calculate shear stresses in beams: the Mohr-Coulomb formula and the Euler-Bernoulli beam theory. The Mohr-Coulomb formula calculates shear stresses using the principle of energy conservation: the shear stress is equal to the strain energy divided by the cross-sectional area. The Euler-Bernoulli beam theory calculates shear stresses using a mathematical equation that takes into account the weight of the applied load and the stiffness of the beam.

To draw a shear stress distribution diagram, first, find out how much weight is applied to a beam, then use that information to calculate how much strain is being applied at each point on the diagram. Next, connect these points with lines to show where all of the stress is being concentrated.

## Course on Shear Stresses in Beams

The course is designed for understanding the concept of Shear Stresses in Beams. At the end of the course, the learners will be able to calculate the values of Shear Stresses at various sections and draw the Shear Stress Distribution Diagram. The most important feature of the course is all types of problems are solved and explained in detail.

The course has a total of 8 video lectures. The very first lecture is all about the course outline, prerequisites for this course, and expected outcomes. The next two lectures are for the concept explanations. The basic concept of Shear Stresses is discussed in brief and the determination of Shear Stresses is explained in detail. Each parameter involved has been explained with the relevant diagrams and animations.

One complete lecture is for explaining, how to draw Shear Stress Distribution Diagram. In the remaining lectures, problems are solved step by step with proper explanations. The problems on all types of cross-sections are included for better understanding. The solved problems include rectangular cross-sections, ‘T’ cress section, symmetric and un-symmetric ‘I’ section. The last problem is designed in order to demonstrate the Shear Force calculation and then Shear Stress calculations.

Shear Stress is one of the important parameters, required to be calculated for the design of beams. Hence this course will definitely equip students with the ability to calculate Shear Stress and draw Shear Stress Distribution diagrams.
