Consider a micro mirror which is tethered by two torsional springs. Mirror and tethers are made of aluminum. Two tethers are fix
ed at the end. The length of tether (L) is 5 µm, thickness (t) is 0.3 µm, and width (w) is 1 µm. Assume that aluminum’s Young’s modulus is 70 GPa and Poisson’s ratio is 0.33. The micro mirror tilts into/out of the page with angle of ± 12°. What is the required torque to make the mirror tilted ± 12°?

Answer:
1 pulse rotate = 9 degree
Explanation:
given data
incremental encoder rotating = 15 rpm
wheel holes = 40
solution
we get here first 1 revolution time
as 15 revolution take = 60 second
so 1 revolution take =
1 revolution take = 4 seconds
and
40 pulse are there for 1 revolution
40 pulse for 360 degree
so 1 pulse rotate is =
1 pulse rotate = 9 degree
