An instantaneous configuration of a four-bar mechanism, whose plane is horizontal, is shown in Figure below. At the given instant assume that the link 2 has only an angular acceleration of 4,5 radian per second square. Links 4 has a mass center at C, a mass of 7,9 kg, and a moment of inertia 0,3-kilogram meter square. The link 2 is balanced so that its centre of mass is at A. It has a mass of 9 kg and a moment of inertia 0,8 kilogram meter square. Link 3 has no mass. (If the direction of the resultant torque is CCW, just enter the value of it without any sign. If it has CW direction, enter the"-"sign "negative sign" before the value such as "- 12,12".) At the instant given, what is the torque on the link 2 (If the direction of the torque is CCW, just enter the value of it without any sign. If it has CW direction, do not forget to enter - sign "negative sign" before the value) ? AB=CD=AD=0.3m BC=0.6m
