The image contains the problem as well as the answers to the previous problems.

**2. Homework Equations**

Net torque = 0

**3. The Attempt at a Solution**

First, I set the axis of rotation to be the bottom of the table (where it goes through F

_{x}and F

_{0})

τ

_{due to downward forces}= τ

_{due to upward forces}

τ

_{vase}+ τ

_{table}+ τ

_{cat}= τ

_{due to Fy}(F

_{y}(the solution to F

_{y}is in the image)

W

_{v}Y + W

_{t}L

_{y}/2 + W

_{max}L

_{y}= W

_{t}/2 + W

_{v}Y/L

_{y}

Rearrange for W

_{max}:

W

_{max}= W

_{t}/2L

_{y}+ W

_{v}Y/L

_{y}

^{2}- W

_{v}Y/L

_{y}- W

_{t}/2

The answer to the question is:

W

_{max}= W

_{v}(1 - X/L

_{x}- Y/L

_{y})

I don't know how to obtain this answer from my answer above.
