3.1 In a translational motion actuator, the A-i relationship is given by i=A32+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. 3.2 The A-i relationship for an electromagnetic system is given by λ= 1.211/2 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.
