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°?

Why is the back-work ratio much higher in the brayton cycle than in the rankine cycle?
zloy xaker [14]

The back-work ratio much higher in the Brayton cycle than in the Rankine cycle because a gas cycle is the Brayton cycle, while a steam cycle is the Rankine cycle. Particularly, the creation of water droplets will be a constraint on the steam turbine's efficiency. Since gas has a bigger specific volume than steam, the compressor will have to work harder while using gas.

<h3>What are modern Brayton engines?</h3>

Even originally Brayton exclusively produced piston engines, modern Brayton engines are virtually invariably of the turbine variety. Brayton engines are also gas turbines.

<h3>What is the ranking cycle?</h3>

A gas cycle is the Brayton cycle, while the Ranking cycle is a steam cycle. The production of water droplets will especially decrease the steam turbine's performance. Gas-powered compressors will have to do more work since gas's specific volume is greater than steam's.
