It also expects the truck to produce up to 663 horsepower (494 kW) and 615 pound-feet (834 N⋅m) of torque, a 0 to 60 mph time of 4.4 seconds, a towing capacity of up to 14,000 pounds (6,400 kg), and a payload capacity of up to 2,625 pounds (1,191 kg).
The power-to-weight ratio (specific power) is defined as the power generated by the engine(s) divided by the mass. In this context, the term "weight" can be considered a misnomer, as it colloquially refers to mass.
In aerospace engineering, payload fraction is a common term used to characterize the efficiency of a particular design. 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 ...
After leaving the path, the payload continues to move due to momentum. Although any device used to propel a ballistic payload is technically a mass driver, in this context a mass driver is essentially a coilgun that magnetically accelerates a package consisting of a magnetizable holder containing a payload. Once the payload has been accelerated ...
Towing capacity for the regular cab Ram 1500 with 3.21 differential is rated at 6,100 lb (2,767 kg) with 17-inch wheels and 5,900 lb (2,676 kg) with 19-inch wheels. Crew Cab and Quad Cab models are rated at 5,700 lb (2,585 kg) and 5,800 lb (2,631 kg) respectively.
In a spacecraft, the destination is usually an orbit, while for aircraft it is their landing location. A higher mass fraction represents less weight in a design. Another related measure is the payload fraction, which is the fraction of initial weight that is payload. It can be applied to a vehicle, a stage of a vehicle or to a rocket propulsion ...
The fraction of payload to the total liftoff weight of the air or spacecraft is known as the "payload fraction". When the weight of the payload and fuel are considered together, it is known as the "useful load fraction". In spacecraft, "mass fraction" is normally used, which is the ratio of payload to everything else, including the rocket ...
Thrust varies with throttle setting, airspeed, altitude, air temperature, etc. Weight varies with fuel burn and payload changes. For aircraft, the quoted thrust-to-weight ratio is often the maximum static thrust at sea level divided by the maximum takeoff weight . [ 2 ]
