To analyze the results of our experiment, we know that sin0° = 0. And when the angle between **r** and **F** is zero, the torque is also zero.

The torque is maximum at angle 90°. Sinθ value is also maximum at this angle.

Torque is again 0 when the angle is 180°. Sine value of the 180° is also zero.

The conclusion is the turning effect or torque is proportional to the sine value of the angle between **r** and **F**. Therefore, torque is proportional to the magnitude of the force applied, magnitude of moment arm and the sine of the angle between them. Therefore,

= rFsinθ

__This is exactly what the vector product is.__ Therefore,

Thus, torque is equal to the vector product of force and moment arm.
