# More rigid bodies HELP!!!! watch

1. A temporary road sign is displacyed on a metal frame, hinged along its top edge. When closed up, each half of the frame is 2 metres high, weighs 20 newtons, and has its centre of mass 0.8 metres from the hinge. The signi a rectangular board weighing 40 newtons and its centre of mass is 0.5 metres below the hinge. The frame is now opened up. If the coefficient of friction between the feet of the frame and the road is 0.6, what is the greatest possible distance apart of the feet of the two halves of the frame?

No matter how many times I try, i do not get the correct answer. Please can anyone help me?
