Designing the right belt feeder
A belt feeder is a critically important element in many bulk material handling systems, since it controls the solids flow rate from a storage vessel (bin, silo, bunker, hopper) or stockpile and can affect live capacity. When the belt feeder stops, solids flow should cease. When it is running, there should be a close correlation between its ...

Shear Forces and Shear Stresses in Structures
There are basically three kinds of crack produce in a concrete, which are: 1. Flexural cracks or cracks due to bending of the beam. 2. Flexural + shear cracks which are caused due to combination of bending and shear forces. 3. Lastly shear cracks which tend to come up near the support due to shear forces.
