The major forces that accelerate a vehicle occur at the tires' contact patches.Since these forces are not directed through the vehicle's CoM, one or more moments are generated whose forces are the tires' traction forces at pavement level, the other one (equal but opposed) is the mass inertia located at the CoM and the moment arm is the distance from pavement surface to CoM.
Weight distribution is the apportioning of weight within a vehicle, especially cars, airplanes, and trains.Typically, it is written in the form x/y, where x is the percentage of weight in the front, and y is the percentage in the back.
In the absence of a net external force, the center of mass moves at a constant speed in a straight line. This applies, for example, to a collision between two bodies. [49] If the total external force is not zero, then the center of mass changes velocity as though it were a point body of mass . This follows from the fact that the internal forces ...
This force acts at ground level, below the center of mass. The force of inertia acts horizontally through the vehicle's center of mass away from the center of the turn. These two forces make the vehicle roll towards the outside of the curve. The force of the vehicle's weight acts downward through the center of mass in the opposite direction.
The payload fraction is the quotient of the payload mass and the total vehicle mass at the start of its journey. It is a function of specific impulse, propellant mass fraction and the structural coefficient. In aircraft, loading less than full fuel for shorter trips is standard practice to reduce weight and fuel consumption.
The families of two New Jersey firefighters who were killed battling a July blaze inside a cargo ship said Friday a malfunctioning vehicle being used to load cargo onto the ship caused the fire.
Authorities in the United States have reviewed airport security footage as they continue to investigate how a woman sneaked on board a Delta Air Lines flight from New York to Paris without a ...
From September 2011 to December 2012, if you bought shares in companies when William J. DeLaney joined the board, and sold them when he left, you would have a 16.3 percent return on your investment, compared to a 18.4 percent return from the S&P 500.
