1 In a translational motion actuator, the A-i relationship is given by i=A+2.5A(x-1)² for 0 < x <1 m, where i is the current in the coil of the actuator. Determine the force on the moving part at x = 0.6 m. 2 The A-i relationship for an electromagnetic system is given by A 1.2/12 g where g is the air gap length. For current i 2 A and g = 10 cm, determine the mechanical force on the moving part (a) Using the energy of the system. (b) Using the coenergy of the system. =
