Cutting speed may be defined as the rate at the workpiece surface, irrespective of the machining operation used. A cutting speed for mild steel of 100 ft/min is the same whether it is the speed of the cutter passing over the workpiece, such as in a turning operation, or the speed of the cutter moving past a workpiece, such as in a milling operation.
One percent more on your mortgage rate might not sound like a lot, but with loan terms that extend for decades, a single percentage point can cost homebuyers tens of thousands of dollars. Jaspreet...
A substance is characterized by a burn rate vs. pressure chart and burn rate vs temperature chart. Higher burn rate than the speed of sound in the material (usually several km/s): "detonation" A few meters per second: "deflagration" A few centimeters per second: "burn" or "smolder" 0.01 mm/s to 100 mm/s: "decomposing rapidly" to characterise it.
The last region is an increasing failure rate due to wear-out failures. Not all products exhibit a bathtub curve failure rate. A product is said to follow the bathtub curve if in the early life of a product, the failure rate decreases as defective products are identified and discarded, and early sources of potential failure such as ...
The origin of the graph is where the airspeed axis crosses the sink rate axis at zero airspeed and zero sink rate. The horizontal line is tangent to the top of the polar curve. That tangent point indicates the minimum sink airspeed (vertical line). The sink rate increases to the left or right of this point, corresponding to a lower or higher ...
The current prime rate is 5.50%, up from 4.75% in June. It went into effect July 28, 2022. This is the fourth time in 2022 that the Federal Reserve has increased the prime rate.
In physics, mechanics and other areas of science, shear rate is the rate at which a progressive shear strain is applied to some material, causing shearing to the ...
The definition of strain rate was first introduced in 1867 by American metallurgist Jade LeCocq, who defined it as "the rate at which strain occurs. It is the time rate of change of strain." In physics the strain rate is generally defined as the derivative of the strain with respect to time. Its precise definition depends on how strain is measured.
