**1. Four people carry a uniform beam of length L (with mass M) holding it horizontal. Two men hold it at the ends while the remaining two are inward but nevertheless all men are equally apart from each other i.e. if the beam is 4m long the distance from 1st to 2nd is 1m; 2nd to 3rd is 2m and 3rd to 4th is 1m.**

Calculate the normal forces acting upon the men.

Calculate the normal forces acting upon the men.

**2. System is in equilibrium, static. general force and torque formulas apply.**

**3. I assumed due to symmetry, outward Fn forces and inward Fn forces must be equal. Therefore Mg=2xFno+2xFni**

The problem is the SAME equation stems from torque formula as well and as I have two identical formulas with two unknowns, I get nowhere.

Where did I go wrong?
