How to solve for static friction
WebOct 1, 2016 · Apply force on the block in horizontal direction till the block just starts to move. This force would be F = μ s M g Once the block starts moving kinetic friction will act on the block. Since coefficient of kinetic friction is numerically less than that of static there will be unbalancing of forces thus causing an acceleration, say a .

If you push horizontally with a small force, static friction establishes an equal and opposite force that keeps the book at rest. As you push harder, the static friction force increases to match the force. Eventually maximum static friction force is exceeded and the book moves. cissp tiger teamWebThe normal force will be equal and opposite to the perpendicular gravity component so N = +mg*cos (Θ). To keep the block from sliding, you would then need to apply a horizontal force equal and opposite to the parallel gravity component so that force would be F = +mg*sin (Θ).
