16-59. The relay switch consists of a thin metal strip of almature AB that is made of red brass C83400 and is attracted to the solenoid S by a magnetic field. Detemine the smallest folce Frequired to attract the afmature at C'in order that contact is made at the free end B. Also, what should the distance a be for this to occur? The afmature is fixed at A and has a moment of incrtia of I-0.18(10 12) m. 2 mm- 50 mm S0 mm

Required information An ergonomically designed key for a computer keyboard has an approximately flat surface defined by points A, B, and C and is subjected to a 1 N force in the direction normal to the key's surface. In the figure, the switch mechanism is repositioned so that the motion of the key is in the direction of the line connecting points D and E, where this line has x-, y-, and z-direction cosines of 0.123, 0.123, and 0.985, respectively. Determine the components of the force in directions normal and tangent to the key's motion. (Round the final answers to four decimal places. Include a minus sign if necessary.) A (15,0, 10) mm z B (0, 0, 15) mm C (0, 15, 12) mm x D B E The component of force in the direction tangential to the motion is The component of force in the direction normal to the motion is N. N.
