Can I set my own bindings?

Weight is the force that is due to gravity, but it's a force all the same so that's why we express weight in units of force: i.e. pounds. Newton is the unit of force in the metric system. Yes, but, generally... Force = Weight And I realize I got my units wrong. Weight is just one particular kind of force (force due to gravity). It's a common force, but not the only one. Weight is force. But force is not necessarily weight. Torque is rotational force, and is expressed as the force times the Almost but not quite. Pound-foot and Newton-meter are measures of WORK which is the movement of a weight or force over a distance. Then Torque is rotational WORK. In this case, a torque wrench operates in a rotational mode. BTW, I actually meant to hit Cancel, but hit Send instead. mea culpa. But, now that I'm in the middle of the argument, torque is force applied at some distance, Yes, but isn't that what WORK/ENERGY is? hence it has units of force X length (i.e. foot-pounds or newton-metres) Work (energy) also has units of force x distance, but to say that torque is equivalent to work is not quite correct. For instance, if I'm trying to unscrew a nut, but can't get the &%^$*! thing to move I may be exerting substantial torque but I'm not doing any work since nothing's moving. Here's where we get into the difference between potential energy and kinetic energy. If the nut doesn't move, the force you are applying is POTENTIAL because no WORK is getting done. If the nut moves, then TORQUE is being applied and, as you say, TORQUE is a form of WORK. You are applying FORCE, but it's not yet TORQUE/WORK because nothing has moved. TORQUE is not a form of FORCE. Torque is not a form of work or energy, although the units are the same. Yes it is. //Walt |
