Equilibrium of two Planks on a Rough Plane: Figure shows two planks inclined to horizontal rough surface and connected by a string. Find the minimum angle (in degrees) for which this system remain in equilibrium if friction coefficient is = 0.5.
For equilibrium of plank, we use
For rotational equilibrium of plank we use torque on plank about any point must be zero.
