find stress at Q
I had a theoretical question about attitude determination. In the attached images, I gave two axis and angles. The coefficient of the axes are the same and the angles are the same. The only difference is the vector basis. Lets say there is a rotation going from n hat to b hat. Then, you introduce a intermediate rotation s hat. So, I want to know if the DCM produced from both axis and angles will be the same or not. Does the vector basis affect the numerical value of the DCM? The DCM formula only cares about the coefficient of the axis and the angle. So, they should be the same right?
3-15. A small fixed tube is shaped in the form of a vertical helix of radius a
and helix angle y, that is, the tube always makes an angle y with the horizontal.
A particle of mass m slides down the tube under the action of gravity. If there is
a coefficient of friction μ between the tube and the particle, what is the steady-state
speed of the particle? Let y
