Question
The circular disk has a mass $m$ and is suspended at $A$ by the wire. If it receives a horizontal impulse $\mathbf{I}$ at its edge $B$, determine the location $y$ of the point $P$ about which the disk appears to rotate during the impact.
Step 1
First, we need to find the forces acting on the disk during the impact. There are three forces acting on the disk: the impulse force $\mathbf{I}$, the gravitational force $mg$, and the tension force in the wire. Show more…
