Question

**Problem Statement:**

For the position shown, the assembly consists of two identical uniform rigid bars, each having a mass \( m \) and length \( l \). The system has a known angular velocity \( \omega \). Determine the pin forces at point \( A \) and the angular acceleration \( \alpha \) at this instant. (Note: The image has a distortion; the bend at \( B \) is \( 90^\circ \).)

**Diagram Explanation:**

The diagram illustrates a system composed of two connected rigid bars, forming a geometric shape similar to an "L" due to the \( 90^\circ \) bend at \( B \).

- The horizontal bar \( AB \) extends to the right from the pin at \( A \).
- The vertical bar \( BC \) extends downward from the bend at \( B \).

Both bars have uniform mass distribution, each denoted by mass \( m \) and length \( l \). Point \( A \) is shown as a pivot point, indicating where the rotational motion originates. The structure suggests a combination of rotational and possibly translational dynamics in the system.

The rod AB is non-uniform with a radius of gyration of 4.00 ft with respect to a horizontal axis through the center of mass G. It weighs 161 lb. At the moment shown the rod has a counterclockwise angular velocity of 3.00 rad/sec, and the spring is compressed by 2.00 ft. Calculate the force constant of the spring that will reduce the angular velocity of the rod to 1.50 rad/sec when it reaches the horizontal position. Assume the blocks A and B are weightless.
A momentum wheel for dynamics class demonstration is show. It is basically a bicycle wheel modified with rim band-weighting, handles, and a pulley for cord startup. The heavy rim band causes the radius of gyration of the 3.1 kg wheel tobe 275 mm. If a steady 32 N pull F is applied to the cord, determien the angular acceleration of the wheel. Neglect bearing friciton.
Consider the wheel shown below with radius R, mass m, and radius of gyration ko¹ The wheel rolls without slipping under the action of a clockwise torque M.
