What are the forces acting on a race car while it starts to move faster? What are the forces acting on a racing car while it slows down around a turn? What are all the forces acting upon a package within a car when a driver slams on the brakes?
In summary, a train engine of mass ##m## is moving at a constant speed ##v## around a circular curve of radius ##R##. To understand the forces acting on the train, a free body/force diagram should be drawn from the perspective of a cross section of the wheel and rail. ...
A constant speed joint has an outer part (1), an inner part (2), a cage (3) and ball bearings (4) transmitting torque between the outer (1) and inner parts (2). The outer (2) and inner (2) parts have different types of ball races, namely first (10) and second (11), and ...
As train speeds increase, the aerodynamic effects generated during the passage of high-speed trains in tunnels become more pronounced. This article investigates the influence of line spacing on the aerodynamic forces during the passage of high-speed trai
