How torque depends on the direction of the force

How can the torque applied to the wrench in the figure be expressed in terms of r , |F|, and the angle θ?

The force vector and its F? component form the hypotenuse and one leg of a right triangle,

and the interior angle opposite to F equals θ. The absolute value of F can thus be expressed as

F = |F| sin θ ,

leading to

|t| = r |F| sin θ .

The quantity r
