    It is a vector because it has direction.

    Thanks, I was thinking that but then again I was thinking of scalar because it seems wierd to say 110 T 89 degrees SofW

    Torque is a vector. But in many introductory problems, the forces all act in a single plane and all that matters is the orientation of the torque (for example: clockwise versus counterclockwise).

    Yeah, we are doing simple questions such as Tcw = Tccw to find out forces, lengths, angles or masses. So that is also why it was confusing me. Thanks both of you.

    yeah it is a vector because it has direction. a scaler only has magnitude whilst a vector has magnitude and direction.
