I'm designing a test fixture and need a compact coaxial electric motor.
The motor drives two counter rotating fans with tip speeds up to 650 fps (desired), 500 fps (required). The fan diameter has not been selected, but is between 2 to 3 ft. Initial estimates suggest that the total fan...
Since derivatives with respect to time are needed, it may be a good idea to keep track of t
For M1
Let x1 be the distance from the circle center to M1. The triangle problem is side(L), side(R), angle (theta) type, and the unknown is the other side. Let gamma be the angle opposite of side L...
There's only one unknown in this problem, so you should only end up with one equation. Lagrange's equations uses energy balance of the kinetic and potential energy, with derivatives of the energy with respect to the fundamental variable. In this case, use theta as the unknown. Write x1 and x2...
