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 A D B E y 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.

In the four-rod mechanism. You have a closed polygon, where: a = length of input crank = 1 inch b = length of connecting rod = 2 inches c = length of output crank = 2 inches d = length of fixed rod = 2 inches. By varying the angle θ, the perimeter of the polygon is preserved, but not its area. Determine the angle θ where its maximum area is reached and the minimum area of the polygon.
