I need to find direction of torque by using right hand rule with the Force vector and R vector ( pointing away from pivot point i think, for rigid body)

Homework Equations

none

The Attempt at a Solution

I put the tails of F and r vectors together, and point thumb away from me, with hand parallel to r vector, and then curl my 4 fingers toward F i get clock wise.


Im not sure if i am right. thanks

Looks good to me. (Assuming I understand your diagram.) To curl your fingers from r towards F, your thumb must point into the page. Thus the torque vector will be into the page, or (equivalently) the torque will be clockwise.
