16-10. The vertical-axis windturbine consists of two
Chapter 17, Problem 16-10(choose chapter or problem)
The vertical-axis wind turbine consists of two blades that have a parabolic shape. If the blades are originally at rest and begin to turn with a constant angular acceleration of \(\alpha_{c}=0.5 \mathrm{rad} / \mathrm{s}^{2}\), determine the magnitude of the velocity and acceleration of points A and B on the blade when t = 4 s.

QUESTION:
The vertical-axis wind turbine consists of two blades that have a parabolic shape. If the blades are originally at rest and begin to turn with a constant angular acceleration of \(\alpha_{c}=0.5 \mathrm{rad} / \mathrm{s}^{2}\), determine the magnitude of the velocity and acceleration of points A and B on the blade when t = 4 s.
ANSWER:
Step 1 of 4
First, determine the angular velocity, w. of the blades. This can be calculated using the equation:
