**Problem 8.** The piston shown is moving downward in its track at 26 cm/sec, as shown in Figure 8. All dimensions are in cm. Determine:
a) The velocity of point B
b) The rotational velocity of link AB

**Explanation of Figure 8:**

The diagram shows a mechanical arrangement with a vertical track on the left side. A piston (or a point, A) is moving downward along this track. A link labeled "AB" is connected to the piston at "A" and extends diagonally downward to the right, ending at point "B" on the horizontal plane. The angles involved are labeled as follows:
- The angle between the track and the vertical link (AB) is 15 degrees.
- A secondary link labeled "C" is connected diagonally at 10 degrees from the vertical link.
- There is an angle of 60 degrees at the base marked where link AB meets the horizontal plane.

Points A, B, and C are marked on the diagram to show positions along the linkages. The diagram provides the necessary angles needed to calculate velocities and rotational velocities through trigonometric and kinematic equations.
