How to calculate and apply stiffness coefficients How to utilize V in a reconstruction ... Upon completion of this course, the student will understand the principles of CRUSH energy analysis and will be able to apply those principles when investigating motor vehicle crashes.
The speed calculated can be COMBINED with other crush speeds and post impact speeds. This DOES NOT calculate a deltaV. It calculates the energy to create the crush, expressed as a speed.

The workenergy principle says that if you have some system, the work done on it is the change in energy of that system.
In primary crushing, it is reduced by a factor of four and in secondary crushing by about five times. Clearly, changes in blasting that reduce grinding requirements will have the biggest impact for energy savings. The work input shown for blasting is calculated by the Bond equation. The actual energy input is .33 kg/ton, or .31 kwh/ton.
The Crush Spread, Crush Profit Margin and Crush Ratio. There are a number of other ways to formulate the crush risk (CME, July 11. 2011): The CBOT defines the "Crush Spread" as the Estimated Gross Margin per Bushel of Corn. It is calculated as follows: 2. Crush Spread = (Ethanol price per gallon X ) – Corn price per bushel, or as. 3.
May 04, 2006· the energy released during a car crash is proportional directly to the speed of the object(s) squared. what this means is that a car traveling at 100 mph will produce 4 times the energy released as opposed to a car traveling at 50 mph although it is only 2 times as fast.
EER(Energy Efficiency Ratio)=cooling capacity of ac/power consumed by ac. Assuming the ac to be a 3 star rated, its Energy Efficiency Ratio ( EER )= Cooling capacity of ton is equal to 5200 kW of power. For ton AC,power consumption of ac =cooling capacity/EER =5200/ =1425 W.
undergoing particle crushing is often assumed to scale solely with the increase in surface area, irrespective of the strain energy stored in the surrounding media.
A motorist exiting a rural freeway was struck by a motorist on the intersecting State Route at the top of the exit ramp. At the westbound exit ramp from the Interstate freeway the State Route a stop sign is posted at the end of the ramp requiring exiting traffic to stop before entering the State Route.
