1. **State the problem:** We want to find the set $W = \{x \in \mathbb{N} \mid 2x \leq 4 \wedge x > 1\}$.
2. **Understand the conditions:** The set $W$ contains natural numbers $x$ such that both $2x \leq 4$ and $x > 1$ hold true.
3. **Solve the inequality $2x \leq 4$:**
$$
2x \leq 4
$$
Divide both sides by 2:
$$
\cancel{2}x \leq \frac{4}{\cancel{2}} \\
x \leq 2
$$
4. **Combine with the second condition $x > 1$:**
We need $x$ such that:
$$
1 < x \leq 2
$$
5. **Find natural numbers satisfying both:**
Natural numbers are $1, 2, 3, \ldots$
Only $x=2$ satisfies $1 < x \leq 2$.
6. **Final answer:**
$$
W = \{2\}
$$
