Question 5 The center of mass of the vertical 775-kg panel is at G. The panel is mounted on wheels which permit ease of horizontal movement along the fixed rail. If the bearing of the wheel at A becomes "frozen" so that the wheel cannot turn, compute the force P required to slide the panel. The coefficient of kinetic friction between the wheel and the rail is 0.55. 600 mm- Answer: P = 2.1 m the tolerance is +/-2% G 1 -2.1 m B N 600 mm 3.9 m P
