Pound Foot per Square Second [lbf·ft/s²]
This unit represents a torque or moment of force per unit time squared (though it’s an uncommon combination and can sometimes be context-specific).
It combines pound-force (lbf), a unit of force, with foot (ft), a unit of length, divided by second squared (s²), a unit of time squared.
It may be used in dynamics or rotational mechanics when dealing with angular accelerations or rate changes of torque.
In basic terms:
1 lbf\cdotpft/s2=force×distance÷time2
1 lbf\cdotpft/s2≈1.35582 N\cdotpm/s2
Ton-Force (Long) [tonf (UK)]
The long ton-force (also called the UK ton-force) is a unit of force based on the long ton, traditionally used in the United Kingdom.
A long ton equals 2,240 pounds (lbs).
The long ton-force is the force exerted by a long ton mass under standard gravity.
Mathematically:
1 tonf (UK)=2,240 lbs×9.80665 m/s2≈9,964.02 newtons
