Unformatted text preview: the outer gear is Fxed. % 6. Given the fourbar linkage in the following diagram where θ 2 = 45 ◦ , r 1 = 600 mm, r 2 = 140 mm, r 3 = 690 mm, r 4 = 400 mm, a 4 = 200 mm, and ∠ BO 4 C = 45 ◦ (constant). a) Write down the loop closure equations. b) Determine the angle, 3 . c) Determine the coordinates of point C. r 3 % % r 1 r 2 r 4 A B C O 2 O 4 x y 3 2 4 a 4 7. Using the NewtonRahpson method, determine the position of the slider for the following offset slider crank mechanism where r 2 = 2 inches, r 3 = 11 inches, e = 1 inch, and θ 2 = 120 ◦ . Start with an initial guess of d = 10 inches and solve for d within 0.001 inches. % A B O 2 x y 3 2 r 3 r 2 d e...
