Pounds per square inch (psi) is a unit of pressure most commonly associated with tire pressure for an automobile or bike tire. However, because pressure gauges are attached to most tire pumps, there's often very little need to calculate psi in this context. People working with hydraulics also...
Engineers calculate the maximum allowable pressure (P) inside a pipe by using Barlow's formula, which relates pressure to the nominal wall thickness (t), the allowable stress (S), which is the SYMS, and to the inverse of pipe diameter (D). The formula is: P = 2St/D The SYMS is us...
How to convert ounces to grams with a formula What will be the gauge pressure and the absolute pressure of water at a depth of 12 meters below the surface? Calculate how much pressure (due to the liquid) would be on a 73-kg person if they were 234 m deep in: a. freshwater. The ...
I will use Pacejka's Magic Formula to get μ as a function of relative slip. Now, how can I calculate the relative slip, I think of RextΩ−v|v| Where Ω is the longitudinal component of rotational speed ω To get ω I would have used v=Rextdθdt because ω=dθdt So ω=vR...
a small, lightweight magnet balanced on a nearly frictionless pivot point. The magnet is generally called aneedle. One end of the needle is often marked "N," for north, or colored in some way to indicate that it points toward north. On the surface, that's all there is to a compass....
This value represents the tire's coefficient of friction while the brakes are locked across a wet surface. Don't get this confused with a hydroplaning rating, it's not. In fact, due to the effectiveness of anti-lock braking (ABS) on modern vehicles, which prevents tires from locking up...
How much material is there to burn following a nuclear exchange? How much would remain in the atmosphere, and how much would fall back to theEarth'ssurface? How much sunlight would such smokecloudsdeflect? During which season would the attack occur? If an attack occurred during the actual wi...
Topographic maps allow you to see a 3-D landscape on a 2-D surface. © HowStuffWorks We're all familiar with maps. They're those pieces of paper we pull out of the glove compartment — those crispy documents that unfold so large our view of the road is completely obstru...
The life-cycle model sizes the aircraft based on the flight distance and year of construction (which conditions improvement factors to apply). Details are given in Aircraft. The approach used to calculate in-flight emissions is described in Surface and flight emissions. The approach used to calcul...
We developed a dynamic model of the system to calculate the parameters shown in Fig. 2F that minimize the damage upon impact during the perching maneuver, described in Supplementary Method 2 and 4. The dynamic model estimates the motion of the system and the stresses in the joints for a give...
