3.3.6 Friction (A-level only)

Question 6

A uniform beam $AB\,$ of length 10 m and mass 20 kg is used as a ladder. End $A\,$ is on rough horizontal ground and the beam rests in limiting equilibrium against a smooth horizontal rail at point $C$ , where $A C = 8$ m. The beam is inclined to the horizontal at an angle $α\alpha$ , where $tan⁡α=15/8\tan \alpha = 15/8$ . The coefficient of friction between the beam and the ground is $μ\mu$ .

Find the value of $μ\mu$ .
