If you don't want a 'science lesson', I suggest you stick to doing some humanities style subjects and drinking lattes with your chardonnay socialist friends in some oohlala cafe in an inner city suburb discussing post modernist whaling in the North Sea. If you cannot grasp 'oldcorolla's' basic yet excellent explanation, then you are beyond help. Harsh but true. garbage. all BAD22 needs to know in the way of concepts, is that torque = twist. "Nm" simply represents a newton (unit of force, like kg) acting at the end of a given distance, in this case 1 metre. this was all covered in previous posts above. its simple leverage, not rocket science. more force at the end of the metre, more twist, more torque. on a side note: torque is often mistaken by those with little or no grasp on the relevent concepts as being more important than power. usually by the same group of people, oddly enough, who think turbos are for small engines only, and/or inferior to superchargers. but i digress. power is what moves a car or object. so what is power? power is work done over time. to understand that you must understand that torque is 1-dimensional; by which i mean you can have torque with zero motion taking place. ie by leaning on a spanner on a jammed nut or bolt, or holding the armature of a small electric motor tightly between your fingers and attaching a battery. if said spanner is a foot long, and you apply 40 pounds of force, youre applying 40ft/lbs of torque to the nut or bolt youre trying to undo/tighten. if it doesnt move, no work is taking place. the second that nut moves, work has been done. power is thus torque x rpm. back to the electric motor. if you have an electric motor that generates 1Nm of torque @ 1000rpm and the same 1Nm at 20,000rpm, it will be making 20 times the power it makes at 1000rpm, even thuogh the torque has stayed the same. as for how newton meters are measured, the only realistic way to measure them (in the automotive sphere of things anyway) is via an engine dyno. chassis dynos measure torque at the wheels, and spit out a (torque) figure which is the result of the cars gearbox and differential. power is calculated from referencing the roller speed against the torque measured at the rollers. this is commonly called tractive force, or effort, at least on a dyno dynamics eddy current dyno. on a dynojet inertial dyno the machine measures hp and calculates a guestimate of torque at the flywheel using inputted data on drivetrain gear ratios.
