7) 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 1N force in the direction normal to the key's surface. The motion of the key is in the Z direction. Determine the components of the force in directions normal and tangent to the key's motion. IN A (15,0, 10) mm B (0, 0, 15) mm C (0, 15, 12) mm
