【實用工具app】A.I. Calculator|最夯免費app

The Accident Investigation Calculator simplifies the task of performing accident / collision investigation ‘equations of motion’ (SUVAT) calculations.

Designed primarily to assist in the investigation of road traffic accidents, the app will also benefit students, engineers, or anyone else who regularly uses these types of equations.

The app does not include an exhaustive list of every possible A.I.formula; instead, it contains over 30 of the most commonly used formulas, selected to provide you with quick results at a scene, and to cover the majority of straight-forward accidents.

(Please note: this is the initial release version of the app – Additional formulas may be added in subsequent versions. If you think something is missing / should be included, please let me know!)

Metric units are used throughout the app; however, imperial units of speed (mph) are catered for.

Key features include:

• Calculated results are automatically populated into other equations, saving the need for unnecessary re-typing.

• Input values can be manipulated with +/- slider bars, with the updated results displayed in real time - Ideal for exploring a range of values, or seeing how variations affect the result.

• 10 memory slots for saving results.

• Speed values can be entered in mph or km/h using the in-built converter.

• Speed results are automatically displayed in both metres per second and mph or km/h.

Formulas Available:

Initial Speed

• From skid marks (to a stop)

• From skid marks (to a known speed)

Final Speed

• From distance and time

• After skidding for a known time

• From skid marks (from a known speed)

• After accelerating/decelerating for a known time

• After accelerating/decelerating for a known distance

• From curved tyre marks (level surface)

• From curved tyre marks (cambered surface)

• From pedestrian throw (minimum)

• From pedestrian throw (maximum)

Distance

• From speed and time

• To skid to a stop

• To skid to a known speed

• Skidded in a known time

• To accelerate/decelerate to a known speed

Time

• From distance and speed

• To skid to a stop

• To skid to a known speed

• To skid a known distance

• To gain/lose speed

• To accelerate from stationary for a known distance

• To fall a known distance

Coefficient of Friction

• From speed and distance

• From sled test

Radius

• From chord and mid-ordinate

Acceleration

• From coefficient of friction

• From change in speed in a known time

• From change in speed over a known distance

• From distance travelled in a known time
