    Default Very interesting TORQUE question!

    First of, did anyone notice a difference in the way torque is represented on a literal level over the years.


    Lets just say you're watching Motor Trend or another automotive based TV program back in 1998 and compare it to a program today.

    Notice any differences, There's one difference and it has absolutely nothing to do with numbers?


    I've been wondering for years now!


    anyone?

    I'm not sure if I understand your question. Please elaborate more please.......

    K series 626. That's right. It's got a K in it.

    Well basically torque was measured in "Foot Pounds"


    Now it's referred to as "Pound Feet" for measurement.


    I would just like to know the reason why they made that adjustment?

    becasue the product of force times distance is torque. thats why they swapped it based of respect to Newton law( thats how he wrote it down as).
    but its the same. just being "politically correct" with their terminology.

    it was something like that.......i think.

    The terms are pretty much interchangeable. I've heard it said both ways for as long as I can remember. I've always said "Pound Feet", myself, though.

    i guess "foot pounds" would be more correct because the length is constant at 1 foot. not that i really care...

    it doesnt matter one way or the other. Its a unit that involves two separate units multiplied so its interchangeable unlike miles/hour which has to be in that order.

    well it does matter because its always going to be only 1 foot. if u want to tighten ur wheel nut to 100ft/lbs of torque, then that would be equal torque to putting a 100lbs weight on the end of a 1 foot long wrench. the 1 foot length being constant is key. just like the time being 1 hour for miles/hour units.

    dude it doesnt matter one bit. 100lb*ft of torque is the same regardless of whether you are pushing 100lbs 1 ft or 1 lb 100ft. Multiplication is commutative, welcome to 7th grade algebra.

    Technically, torque is the cross product F x r, which yields a vector. Cross products are not commutative. That's just technicalities, though.

    When I hear pound-feet, I think of a motor's torque. When I hear foot-pounds, I think of torquing bolts. I suppose that if we consider the definition F x r, the correct unit is pounds x foot, and they just don't say "cross" out loud?

    I think it would have more to do with being pleural. One foot pound, many pound feet.
