4 dni temu · \(D_1\) is the distance from the effort force to the fulcrum (m), \(D_2\) is the distance from the fulcrum to the resistance force (m). Example Calculation. For example, if you have an effort force of 100 N applied 2 meters from the fulcrum, and the distance from the fulcrum to the resistance is 4 meters, the resistance force would be:
4 dni temu · \(L\) is the distance between the extremes of any group of 2 or more consecutive axles (in inches), \(N\) is the number of axles in the group. Example Calculation. Consider a bridge segment with a distance of 120 inches between the extreme axles of a vehicle having 4 axles. Using the formula:
5 dni temu · The GSD calculator will determine the ground sample distance for photogrammetry and aerial surveying purposes. Modern drone technology enables mapping croplands for longer periods of time (see drone flight time calculator).. Aerial surveying is a method of collecting geomatic data using aircraft, drones, or balloons.
2 dni temu · The development of the wheel speed calculation incorporates principles from classical mechanics, established by scientists like Isaac Newton. Calculation Formula. The formula to calculate wheel speed in mph is given by: \[ \text{Wheel Speed (mph)} = \frac{\text{RPM} \times \text{Wheel Circumference (inches)}}{63360} \times 60 \]
5 dni temu · The study of braking distances integrates principles from classical mechanics, which have been developed and refined over centuries. Understanding how friction and gravity affect motion is essential in various engineering and safety analyses. Calculation Formula. The formula for calculating the braking distance (\(d_{\text{制动}}\)) is given by:
3 dni temu · The 1 in 60 rule is a rule of thumb used in aviation navigation, primarily for correcting course deviations. This rule states that for every 60 nautical miles flown, a one-degree deviation from the planned course track will result in being one nautical mile off track. Historical Background. The 1 in 60 rule has its roots in basic trigonometry.
