![<Rotation of a rigid body
Torque about the z Axis
Learning Goal:
To understand two different techniques for computing the
torque on an object due to an applied force.
Imagine an object with a pivot point p at the origin of the
coordinate system shown (Figure 1). The force vector F
lies in the xy plane, and this force of magnitude Facts
on the object at a point in the xy plane. The vector 7 is
the position vector relative to the pivot point p to the point
where F is applied.
The torque on the object due to the force F is equal to
the cross product 7 =7 x F. When, as in this problem,
the force vector and lever arm both lie in the xy plane of
the paper or computer screen, only the z component of
torque is nonzero.
When the torque vector is parallel to the z axis (7 = Tk),
it is easiest to find the magnitude and sign of the torque,
T, in terms of the angle between the position and force
vectors using one of two simple methods: the Tangential
Component of the Force method or the Moment Arm of
the Force method.
Note that in this problem, the positive z direction is
perpendicular to the computer screen and points toward
you (given by the right-hand rule ix j = k), so a
positive torque would cause counterclockwise rotation
about the z axis.

Moment arm of the force
In the figure, the dashed line extending from the force vector is called the line of action of
F. The perpendicular distance rm from the pivot point p to the line of action is called the
moment arm of the force.
