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 ...
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...
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...
land surface — its topography — on the map. Here's a cool way to understand how to interpret contour lines: Take an object like a ball or a pile of laundry, and shine a red laser pointer along the object's side. The line you see will look like a contour line on a topographic ...
Now, how can I calculate the relative slip, I think of $$\frac{R_\text{ext}\Omega - v}{|v|}$$ Where ##\Omega## is the longitudinal component of rotational speed ##\omega## To get ##\omega## I would have used ##\displaystyle v = R_\text{ext}\frac{\text{d}\theta}{\t...
Its relatively small surface area of 0.81 sq in resulted in a very high unit pressure (PSI) on drilling surface. Hence the concrete material was removed rapidly. The sight affects was fast wearing of the diamond core bit section. This was specially true at higher horsepower levels on reinforce...
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...
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...
