The structure shown consists of two uniform legs, each having the same mass per unit length of 10.3 kg/m. The leg BC connects to the other leg via a pin-joint at B, such that free rotation at B is possible. If the smallest value of the angle 0 for which the structure will remain in static equilibrium is 58.7 degrees (i.e. slipping does not occur at either contact point A or C), calculate the coefficient of static friction, assuming the same value at both contact points A and C.
