Fill in known fields then click a Compute button to calculate unknown. Main equation:
F = m * Rcg * ω * ω
"When the fields are green, the data is clean!"
Equations used:
Units: N, kg, m, rad/s, m/s, J
EQ1: F = m * Rcg * ω * ω
EQ2: vt = Rtip * ω
EQ3: KErot = I * ω * ω / 2
EQ4: I = m * L * L / 12 + m * Rcg * Rcg
EQ5: L = 2 * (Rtip - Rcg)
When you change a value, it's background is colored light blue.
Entering just a number without units uses the last active units.
Entering just units without a number converts the value to those units.
To see the available (case-sensitive) units, hover over the text fields on the left.
After processing each button press, the "Compute F" button is pressed internally.
After each Compute button press, the "Additional parameters" are recalculated.
The first four Compute buttons use EQ1. The remaining buttons use EQ2-EQ5.
With regards to "I" moment of inertia EQ9, the blade is treated as a long thin rod.
