1. A rod has a mass of 100 kg with a length of 2 m. In the instant shown, θ = tan(3/4) and dθ/dt = 2 rad/s. Determine: (a) What static coefficient of friction must be between the rod and the ground to prevent slipping? (b) If at the instant shown the rod just began to slip with a kinetic coefficient of friction k = 0.2, what is the acceleration of the rod at the mass center G?
