**Educational Exercise: Rotational Motion of a Wheel** **Introduction** The 14-kg wheel shown in the figure has a radius of gyration \( k_g = 200 \, \text{mm} \). The wheel is subjected to a moment \( M = (5t) \, \text{N} \cdot \text{m} \), where \( t \) is in seconds. **Figure Description** The figure depicts a wheel with four spokes and a central hub labeled \( A \). A moment \( M \) is applied, indicated by a curved arrow showing the direction of rotation. **Part A** Task: Determine the wheel's angular velocity when \( t = 3 \, \text{s} \) starting from rest. - Express the angular velocity \( \omega \) in radians per second rounded to three significant figures. - Solution Box: \( \omega = \boxed{56.2} \, \text{rad/s} \) - Note: The response here is marked incorrect; the user has 4 attempts remaining to correct it. **Part B** Task: Calculate the reaction \( A_x \) exerted by the fixed pin \( A \) on the wheel during motion. - Express your answer to three significant figures and include appropriate units. - Solution Box: \( A_x = \text{Value} \, \text{Units} \) **Part C** Task: Calculate the reaction \( A_y \) from the fixed pin \( A \) on the wheel during motion. - Express your answer to three significant figures and include appropriate units. - Solution Box: \( A_y = \text{Value} \, \text{Units} \)
