Shorter rods, revised shorter stroke crank = lower compression. Anything that makes the combustion chamber larger will lower the compression ratio if the pistons travel a shorter distance and do less "compressing". Therefore a crankshaft with reduced stroke is what you need to reduce the compression...
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 use psi, often to determine the amount of force that potable water or waste water ...
Now that we know what these numbers mean, we can calculate the overall diameter of a tire. We multiply the tire width by the aspect ratio to get the height of the tire. Tire height = 235 x 75 percent = 176.25 mm (6.94 in) Then we add twice the tire height to the rim diameter. ...
How can you use mechanical advantage and velocity ratio to determine the efficiency of a lever? Explain how electrical equipotentials are experimentally measured. What is the dimensional formula of stress? How does a clamping circuit change the input waveform? How...
calculate Conventional jet fuel vs. synthetic jet fuel We analyze two technology options: the European aviation fleet relies on fossil-based jet fuel (Fig.2) or syn-jet fuel with a blend volume percentage increasing from 5% in 2030 to 63% in 2050 and 100% by 2063 (Fig.3). In both cas...
The testing system records the force that is needed to stretch the material and the suitable displacement of the grips. Engineers measure the original cross-sectional area of a specimen and the original length between the grips. After that, they are able to calculate stress from the force data...
To calculate the temperature at the center of the chip, the following conditions were set: x = a/2 and y = b/2. Furthermore, diffusivity in the radial and tangential directions were assumed to be very similar since they are both against the wood grain, and α x was set equal to α...

This calculation assumes that the cross-sectional area of the tank is so large compared to the cross-sectional area of the pipe that if you divide the area of the pipe by the area of the tank, the ratio will be close to zero.
Flapping wings produce lift and thrust in bio-inspired aerial robots, leading to quiet, safe and efficient flight. However, to extend their application scope, these robots must perch and land, a feat widely demonstrated by birds. Despite recent progress,
