Question

The length of link DC is LDC = 0.5m and the length of link CB is LCB = 1.7m . Link CD is rotating with an angular velocity of ωDC = 5
rad/s
. Points D and O are fixed.

1-Find the Angular Veclocity of CB

2- what steps would you take to find the acceleration of
point A? Write out the equations you would use symbolically (letters, not numbers). What
additional information would you need? No Need to calculate it

3- What is the velocity of point B in
m/s?

The diagram illustrates a mechanical linkage system comprised of several key components and dimensions:

1. **Wheel and Arm Assembly:**
   - A wheel is depicted at the left side, with a marked point A on its rim.
   - The wheel has a center denoted by point O and a radius of 0.3 meters.
   - A connecting arm, segment OB, extends horizontally from point O to point B, which is attached to the wheel at the center.

2. **Linkage:**
   - The arm continues from point B to point C, identified as segment LC_B. This segment is aligned horizontally and forms a straight line with OB, marking the overall linkage length.

3. **Second Arm and Angle:**
   - From point C, another arm extends to point D, shown as segment LC_D.
   - This arm forms an angle of 60 degrees with the horizontal segment LC_B.

4. **Angular Velocity:**
   - The diagram indicates an angular velocity, denoted by ω_D_C, showing the rotation direction with a curved arrow, suggesting a clockwise rotation.

This setup exemplifies a mechanical system in motion, which might represent principles in rotational mechanics or robotic arm design.
