Determine the vertical component Cy and its direction at C (use "up" or "down"); enter your answer as a whole number. b. Determine the vertical component Ay and its direction at A (use "up" or "down"); enter your answer as a whole number. Example If Cy=300.5 N in the positive direction and if Ay=200.3 N in the negative direction, enter 301up;200down in that order. B C

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.

Referring to the figure, calculate for the following:a) Component of the 800 N force in the x-direction.b) Component of the 400 N force in the y-direction.c) Component of the 450 N force in the direction of the line of action of the 800 N force.
