- Homework Statement
- For a translating block with slipping find the maximum force F to cause no tipping

- Relevant Equations
- Ig*alpha = sum of moments

For this translating block problem, below is the solution. I was wondering why if I took the moment about the center of gravity G, the answer for F would no longer be the same because ##I_G \alpha = -\mu_k N (h/2) + N (b/2) - F*d = 0## because ##\alpha = 0##

$$F = \frac{-\mu_k mg (h/2) + mg(b/2)}{d}$$

What am I doing wrong by taking the moment about G though?

$$F = \frac{-\mu_k mg (h/2) + mg(b/2)}{d}$$
