The ......component of force does not contribute to its torque.

Explanation

To solve the question, "The ......component of force does not contribute to its torque," we need to understand the concept of torque and how different components of force affect it.

### Step-by-Step Solution:

1. **Understanding Torque**:
Torque (\( \tau \)) is defined as the product of the force (\( F \)) and the perpendicular distance (\( r_{\perpendicular} \)) from the axis of rotation to the line of action of the force. Mathematically, it can be expressed as:
\[
\tau = r_{\perpendicular} \times F
