A model of the carriage is shown in the figure. The carriage is being marshalled on a flat horizontal surface. To that aim, a cable, with configuration as shown in the figure, is connected to the carriage and a constant cable force is exerted of F = 5 kN. The carriage starts from rest, and its wheels are in a condition of pure rolling. English: Compute the speed of the carriage at the moment it has been moved over a distance of 2 m.

Applied Fluid Mechanics

A fluid is a substance that is continuously deformed by the application of shear stress. The rate of deformation of a fluid depends on its viscosity. The fluid tries to flow when it interacts with some other system.

Question

English: A train carriage consists of a car body and two axles with wheels. The car body has a mass M =
640 kg. The axles are positioned at a distance of l = 6.2 m; each wheelset (axle + two wheels) has a total
mass of mw = 375 kg and a radius of gyration k = 0.29 m; the wheel radius is rw = 0.45 m. A model of the
carriage is shown in the figure. The carriage is being marshalled on a flat horizontal surface. To that aim, a
cable, with configuration as shown in the figure, is connected to the carriage and a constant cable force is
o exerted of F = 5 kN. The carriage starts from rest, and its wheels are in a condition of pure rolling.
