Hello,
I have a project in which I have to estimate or calculate a metal shaft tilt angle, I have as data the two forces applied on the shaft and which vary according to the tilt of the shaft, and therefore my center of interest is to calculate the force
F = fx * cos (θ) + fy * sin (θ)
knowing that fx and fy are known which are the applied force measured by sensors and that o the angle of inclination of the shaft in degree. I tried to make a model with as input the forces fx and fy at each moment and as output I calculate the force given that I already know the angle θ.
could any one tell me the method of making model or estimating this angle.

Hi,
Yes this is it. by knowing only fx and fy i want to calculate the force F which depande of theta.
F = fx * cos (θ) + fy * sin (θ)

Hi
It seems, theta is unknown here. You can vary theta and calculate F at different value of theta. For example, vary theta as
theta = 0:0.1*pi:2*pi;
% then calculate F
Without knowing theta, actual value of F cannot be determined.
