The pound-force is a non-SI unit of force or weight (properly abbreviated "lbf" or "lbf"). The pound-force is equal to a mass of one pound multiplied by the standard acceleration due to gravity on Earth (which is defined as exactly 9.806 65 m/s², or exactly 196,133/6096 ft/s...
Calculate position of center mass. Center of Gravity and Buoyancy Stability - the center of gravity vs. the center of buoyancy. Centrifugal Pumps - Speed Torque Curve The characteristic speed torque curves for centrifugal pumps. Centripetal and Centrifugal Acceleration Force Forces due to circular...
lbs and kg are measures of mass. In ordinary life we experience mass mostly by its weight, which is a force. A mass of 1 kg is what a scale shows as a weight of 1 kg, but physically it is the force of 1 kg mass pulled by the standard gravity acceleration (9.8 m/sec²) = ...
These force units belong to the gravitational metric system and are based on the pond unit which is defined as the force generated by a 1 gram mass, accelerated by the earths standard acceleration due to gravity of 9.80665 m·s-2.
Gravity is a non-contact force pulling objects towards the earth. 1 Torque Torque is a measure of rotational force. The torque applied to the lug nut allowed the mechanic to remove the tire. 3 Force In physics, a force is any influence that, when unopposed, will change the motion of an...
ag = acceleration of gravity (m/s2) dh = elevation for acting gravity (m) p = pressure on a surface A, or in a volume (Pa, N/m2) A = surface for acting pressure (m2) dV = change in volume for acting pressure p (m3) Power vs. Work Power is the ratio of work done ...
Hydrostatic pressure is the pressure of fluid caused by the force of gravity. It is an important factor not only in engineering and physics, but also in medicine. For example, blood pressure is the hydrostatic pressure of blood on the blood vessel walls. It usually refers to arterial pressure...
(This is particularly important in any problem involving mechanical vibrations, as we will see when we come to Chapter 7.) This takes us to the magic number of 9.807 (m s–2), which is an agreed “standard” value of the acceleration due to gravity at the Earth's surface (referred to...
1 kilogram force (kgf) was the force of gravity, which is pushing a mass of 1 kg at one place in the world on the ground; calculated according to Newton's law force = mass × acceleration. Since the acceleration is dependent on the location, the weight force is varying. Usually, howev...
pounder- (used only in combination) something weighing a given number of pounds; "the fisherman caught a 10-pounder"; "their linemen are all 300-pounders" gee,g-force,g- a unit of force equal to the force exerted by gravity; used to indicate the force to which a body is subjected whe...
