Dielectric Strength: Units, Test Methods & Material Table
Dielectric Strength. Dielectric Strength reflects the electric strength of insulating materials at various power frequencies. Or it can be defined as the measure of dielectric breakdown resistance of a material under an applied voltage and is expressed as Volts per unit thickness. It is an indicator of how good an insulator a material is.

Tensile strength of paper | pulp paper mill
The tensile strength is the maximum stress to break a strip of paper sheet. It is one of the most important basic physical properties of paper and paperboard. The tensile strength is different basis on fiber direction. Since the fiber orientation is dissimilar between machine direction (MD) and cross direction CD), hence the tensile strength is ...
Milling: Design Rules - eFunda
Design milled areas so that the end mill required is limited to 3:1 in length to diameter ratio. As shown in the figure below, longer end mills are prone to chatter.

3.2 Shaft speed. The 2nd key design and operational aspect for a hammer mill is the rotation speed. As the milling principle is based on the energy of the impact, the higher the speed, the finer the product can be expected as the particles will hit the hammer at high speed, but also be sent against each other or against the screen at high speed.
