The flywheel has a diameter of 600 mm and rotates with increasing speed about its z-axis shaft.

Question:

The flywheel has a diameter of 600 mm and rotates with increasing speed about its z-axis shaft. When point P on the rim crosses the y-axis with θ = 90°, it has an acceleration given by a = −1.8i − 4.8j m /s2. For this instant, determine the angular velocity ω and the angular acceleration α of the flywheel.
