Thanks berkeman, Yes this is background for homework! statements, pros & cons -
1. Accelerometer give signal based on linear acceleration or tangential if at the edge of a spinning obj (like the drawing above) - So accelerometers react to linear/tangential forces, which also include Gravity...
Summary:: accelerometer Vs gyroscope - measuring torque
Torque can be measured with an accelerometer (tangential-acceleration):
t = F*r and F=m*a, so we get a from the accelerometer, giving:
t = m*a*r Nm
Torque can be measured with an gyroscope (angular-acceleration):
t = F*r
The...
