No Image AvailableDifferentials and Axles  (34 companies)A differential is a mechanical connection that translates rotational motion from a source to two axles. The driveshaft generally runs the length of the vehicle, from the energy input (a motor) to the energy output (the wheels). The axle of the driving wheels is split, with the driveshaft transferring motion through gearing arrangements to maintain a uniform direction and speed of the (live) axles. This arrangement is very common in rearwheel drive cars and trucks, but is also employed in aircraft, production machinery and equipment, trains, and ships. Learn More

IHS ESDU
Stability of any system that can be modelled ESDU Dynamic. The treatment of stability, response and controllability of any system that can be modelled, for some part of its motion, by linear constant coefficient differential equations. ESDU Dynamics is a treatment of the behaviour and motion of a system and the resulting stability and controllability of that system, particularly under nonsteady conditions where the dynamic nature of the system plays an important part in determining its behaviour. There are a couple of sections within... (read more)Browse Standards and Technical Documents Datasheets for IHS ESDU 
Epoxy Technology
Tech Tip 13  Surface Preparation In adhesive bonding the epoxy is only one part of the equation. Each substrate that is being adhered to is often as important as the adhesive selection. Physical properties such as bond strength, conductivity, and bond reliability all hinge on the interface between substrate and adhesive. The adhesivesubstrate interface is a sensitive equilibrium that can be upset by even the slightest contaminants. In preparing a surface for adhesive bonding users can increase reliability and productivity... (read more)Browse Epoxy Adhesives Datasheets for Epoxy Technology
