AI Thread Summary
The discussion focuses on calculating the g-forces experienced at the tip of a wind turbine rotor with a 253-foot diameter and a rotation time of 3.3 seconds. The calculated tip speed is 229 mph, prompting a query about whether this information is sufficient for g-force calculations. The formula for acceleration is provided, indicating that it can be calculated using either angular velocity or linear velocity divided by radius. Emphasis is placed on using SI units to avoid errors in calculations. Accurate calculations can determine the g-forces at the rotor tip effectively.

i observed a wind turbine w/ 253' diameter rotor (according to website http://www.hcpd.com/powerresources/wessingtonspringswindfarm/ ) and timed rotation was 3.3 seconds. if my calculations are correct the tip speed was a whopping 229 mph!

is this enough info to calculate g forces at the tip?

any insight appreciated 1953greg

The acceleration is omega squared times the radius, where omega is the angular velocity.
OR you can use velocity squared divided by radius.
Be careful to keep your units right - use SI units and you are less likely to go wrong.
 

Thread 'Derivation of Hamilton's Principle: Questions'

I have recently been really interested in the derivation of Hamiltons Principle. On my research I found that with the term ##m \cdot \frac{d}{dt} (\frac{dr}{dt} \cdot \delta r) = 0## (1) one may derivate ##\delta \int (T - V) dt = 0## (2). The derivation itself I understood quiet good, but what I don't understand is where the equation (1) came from, because in my research it was just given and not derived from anywhere. Does anybody know where (1) comes from or why from it the...
