factor of adhesion造句
例句与造句
- Their factor of adhesion is low, so they were prone to slipping.
- The K5's factor of adhesion was much worse than the K4s '.
- The I1s'tractive effort was a little higher, while the N1s had a superior factor of adhesion.
- The wheel arrangement provided a powerful layout with all engine weight as adhesive weight, which maximised the tractive effort and factor of adhesion.
- The amount of force that can be applied to the rail depends on the weight on driven wheels and the factor of adhesion of the wheels against the track.
- It's difficult to find factor of adhesion in a sentence. 用factor of adhesion造句挺难的
- Factors of adhesion below 4 are often considered undesirable for steam locomotives, and the K5 design did prove to be rather less sure-footed because of it.
- However, in heavy freight service they were somewhat less successful, as their relatively light weight and low factor of adhesion caused them to slip on heavy loads.
- The frame was longer than the K3, with a design boiler pressure of giving a tractive effort of, and an estimated factor of adhesion of 3.92.
- The locomotive proved prone to slipping, because its factor of adhesion was very low; in simple terms it was too powerful for its ability to grip the rails.
- They proved that building a larger Pacific than the K4s was not worthwhile; the reduced factor of adhesion limited the locomotives'ability to put their greater power to full use.
- Its high tractive effort and limited adhesive weight ( due to axle load constraints and only two powered axles ) combined to produce a less than ideal factor of adhesion of 3.5.
- They were put to work on goods services on steeply graded branch lines where their superior tractive effort ( 45 % higher than that of the Dd class ) and high factor of adhesion were put to good use.
- Although the J class produced the same nominal tractive effort as the K or N class, they had a slightly higher adhesive weight ( and as such a better factor of adhesion ) and were permitted to haul heavier loads on gradients.
- The " factor of adhesion ", being the weight on the driven wheels divided by the theoretical starting tractive effort, was generally designed to be a value of 4 or slightly higher, reflecting a typical wheel-rail friction coefficient of 0.25.
- A locomotive with a factor of adhesion much lower than 4 would be highly prone to wheelslip, although some 3-cylinder locomotives, such as the SR V Schools class, operated with a factor of adhesion below 4 due to their smoother power delivery.
