Kinematics and Dynamics of Machinery SOLUTION MANUAL 3-44-1 PROBLEM 3-44 Statement: Find the three geared fivebar cognates of the linkage in Figure P3-12. Given: Link lengths: Coupler point data: Ground link L 1 1.82  Crank L 2 0.72  A1P 0.97  54.0 deg  Coupler L 3 0.68  Rocker L 4 0.85  Solution: See Figure P3-12 and Mathcad file P0344. 1. Calculate the length BP and the angle  using the law of cosines on the triangle APB . B1P L 3 2 A1P 2 2 L 3 A1P cos   0.5  B1P 0.792 acos L 3 2 B1P 2 A1P 2 2 L 3 B1P  82.0315 deg 2. Use the Cayley diagram (see Figure 3-24) to calculate the link lengths of the two cognates. Note that the diagram is made up of three parallelograms and three similar triangles L 5 B1P  L 5 0.792 L 6 L 4 L 3 B1P  L 6 0.990 L 10 A1P  L 10 0.970 L 9 L 2 L 3 A1P  L 9 1.027 L 7 L 9 B1P A1P  L 7 0.839

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
