    a common thread spool rests on a flat table. you gentyly pull at an angle on a short piece of thread attached to the spool that causes the spool to slide withouut rotating. with the thread arm at this ange the lever arm is??

    a- small, but not zero, and the torque is zero
    b- perpendicular to the applied force
    c-small and the torque is also small
    d-zero and their is no torque produced by your pull

    Is such a thing physically possible?

    I think that the angle would be 45 degrees because in this problem, with a frictionless table, sinx = cosx

    Is the table frictionless?
