what are the units for torque?

Question

here are the options...?
please help

1)1/s^2
2)kg m2/s^2
3)kg m2/s
4)m/s
5)none of the above

Answer 1

torque = (moment of inertia) * rotational acceleration
= kgm^2 * s^-2
= kgm^2/s^2

so the answer is 3)
Important
additionally remember that N = kgm/s^2
so units of torque can also be written as Nm

Answer 2

Torque Units

Answer 3

Torque is simply a measure of force acting over some leverage arm. Thus, Fd = T; where F is the force acting perpendicular to a lever arm d distance (meter or feet) from the fulcrum.

Thus pound-feet or Newton-meters are appropriate units. But F = ma; so the SI units for Newtons (F) are kg and m/sec^2. Thus, for Fd = T = kg(m/sec)^2, which I think is what you meant with (2).

BTW, Fd = T = slugs(ft/sec)^2 in English units consistent with pounds as the force.

Answer 4

It's number 2 because the SI units for torque is Newton times meter which is eqivalent to kg times 2meters per second squared

Answer 5

In SI Newton metres. Which are dimensionally equivalent to Joules. Which is answer...
