Fx Data (Longitudinal Force)

This figure shows the Fx (longitudinal force) data.

• The offset in Fx after zeroing the SWIFT sensor is due to frictional force

and rolling resistance on a flat road.

• There is a strong similarity between Fx and Mz, due to the SWIFT sensor

measurement characteristics. That is, the SWIFT sensor measures at the

transducer centerline. As a result, any Fx load results in an additional Mz

output:

Mz due to Fx loading = Fx load x Distance
