What is Shear Strength

Theories of failure In order to understand shear strength understanding different theories of failure are important Generally for brittle materials the cause of failure is due to a force in tension For ductile materials the cause of failure is often due to shearing forces The stress strain curve for these two types of material is different.

Introduction to Optical Prisms

Prisms are solid glass optics that are ground and polished into geometrical and optically significant shapes The angle position and number of surfaces help define the type and function One of the most recognizable uses of prisms as demonstrated by Sir Isaac Newton consists of dispersing a beam of white light into its component colors Figure 1 .
