Question 2

A uniform ladder $A B$ , with length 4 m and mass 12 kg, rests with its end $A\,$ on rough horizontal ground. The ladder is in limiting equilibrium against a fixed smooth horizontal rail at a point $C$ , where $A C = 3$ m. The ladder is in a vertical plane perpendicular to the rail and is inclined to the horizontal at an angle $α\alpha$ , where $tan⁡α=4/3\tan \alpha = 4/3$ . The coefficient of friction between the ladder and the ground is $μ\mu$ .

Using the model, find the value of $μ\mu$ .
