CONVERSIONS 1 foot-pound force is:
UNIT OF WORK OR ENERGY To calculate a foot-pound ''force'', you can use this formula,
where W is work (in foot-pound ''force''), '''F''' is Force (in Pound ''force''), And '''d''' Is [[distance (in Feet ) over which the force is applied (measured in the direction of the force). ORIGINS OF FOOT-POUND FORCE Foot-pound ''force'' is derived from the original equation of KE = wz. Where as KE is kinetic energy, w is the weight of the body and z is the average velocity of the falling body times the time of that fall. These are the factors for w.
Where as w is weight, m is mass, g is the local acceleration of gravity and g''c'' is the dimensional constant. These are the factors for z.
Where as z is the average velocity of the falling body times the time of the fall, ½ is the coefficient to find the average velocity, v is the velocity and t is the time of fall. When wz is fully factored to its four UOM (Units of measure)than reduced, the two remaining factors left are F and d. With these two variables left, this proves mathematically that energy of motion is force through distance, as in the original experiment of the two falling objects; force though distance The four UOM are F (pound ''force'') , d (foot) , m mass (pound ''mass'') , t time (second). UNIT OF TORQUE The foot-pound ''force'' is also the unit of Torque , which is conventionally expressed in SI units as Newton-meters rather than joules. Sometimes the order of the units is reversed for torque, expressed as poundral rather than foot-pound ''force''. SEE ALSO |
