Okay. Go on....

Angle of the inclination of the wedge $$\theta$$, spring constant is $$k$$, mass of the cylinder is $$m$$ and its radius is $$r$$. The surface is rough and the cylinder rolls without slipping. We have to find the maximum possible elongation of the spring.

3. mathmate

If this Is a statics problem, then equilibrium is achieved when the spring force equals the downward component of the weight, $kx=mg\ \sin(\theta)$so$x=\frac{mg}{k}\sin(\theta)$

hmm nope that isn't the answer
