This video is an introduction to shear force and bending moment diagrams. What are Shear Forces and Bending Moments? Shear forces and bending moments are resultants which are used to conveniently ...

Stresses in beams are one of the most fundamental concepts in structural engineering, directly impacting the safety and ...

This shear force is directly responsible for the shear stress τ on the x-face of a stress element at “a” in the positive y-direction. In class, we have used the Euler-Bernoulli theory of beams to ...

Understanding Shear Force. Shear force is any force corresponding to a material’s surface. In liquid, for example, this leads to friction between fluid particles, leading to particle size reduction.

The resulting transient hydrogel has good mechanical properties, even when compared to permanent hydrogels, in that it is highly stretchable (it can be stretched up to 30 times its original length).

The force needed to slide sheets of graphene across each other has been measured using a new technique that involves blowing air bubbles made of the material. Developed by Zhong Zhang of the National ...
