Tractive develops and sells GPS & Health trackers for dogs and cats that enable pet owners to view their pet's real-time location, receive Health Alerts, and monitor activity and sleep patterns via a smartphone app. Tractive tracks around 1,000,000 pets in over 175 countries worldwide using GPS and GSM technology.
To establish the "largest" category, several factors take precedence: overall weight, which gives traction over driving axles; size (length and height of engine itself); and power, which may be in terms of raw horsepower, tractive effort, available power at axles (shaft horsepower) or, in the case of steam locomotives, available steam on a ...
The term tractive effort is often qualified as starting tractive effort, continuous tractive effort and maximum tractive effort.These terms apply to different operating conditions, but are related by common mechanical factors: input torque to the driving wheels, the wheel diameter, coefficient of friction (μ) between the driving wheels and supporting surface, and the weight applied to the ...
Traction can also refer to the maximum tractive force between a body and a surface, as limited by available friction; when this is the case, traction is often expressed as the ratio of the maximum tractive force to the normal force and is termed the coefficient of traction (similar to coefficient of friction).
With a tractive effort of 58,110 pounds, the class proved to be nearly twice as powerful as the F-15 Class Pacifics. Unfortunately, the small driving wheels and large rods made the trio rough riders and resulted in a high amount of hammer blow to the track. The fact that the crank was on the third axle did not help to ameliorate the issue.
Drawbar pull is the difference between tractive effort available and tractive effort required to overcome resistance at a specified speed. Drawbar pull data for a vehicle is usually determined by measuring the amount of available tractive force using a dynamometer , and then combining that data with coastdown [ 1 ] data to obtain the available ...
The coefficients for these equations are determined with experiments by measuring the tractive effort from the locomotive at different constant speeds or with a coasting experiments (the rail vehicle is set in motion at a certain speed and then the traction is disengaged, causing the vehicle to stop due to resistance).
The calculated tractive effort was 147,200 lb (66,800 kg) in compound, or 176,600 lb (80,100 kg) in simple for the Virginian locomotives. [ 2 ] The class remained in service until the 1940s.
