1. The problem statement, all variables and given/known data

what distance x from the axis of variation O should be 1 kg
slider, the system oscillations period is 0.9 s?

T=0.9 s;
the spring stiffness k=75 N/m;
slider mass m=1 kg;
beam mass m=3 kg;

2. Relevant equations
I$\varphi$(over letter "..")+k$\varphi$=0
$\varphi$(over letter "..")+$\omega$^2$\varphi$=0

3. The attempt at a solution
