Rotating and reciprocating balance is also solved by employing graphical and analytical techniques. Velocity in Mechanisms (Relative velocity Method). Ordinary Differential Equations 4. 5) is rewritten as (¯x1 – x¯ ∗) · (¯x1 – x¯ ∗) = (Ai x¯ 1 + a¯ i – x¯ ∗) · (Ai x¯ 1 + a¯ i – x¯ ∗), Substituting for Ai and a¯ i gives x1 – x∗ x1 – x∗ x1 cosθi – y1 sinθi + aix – x∗ x1 cosθi – y1 sinθi + aix – x∗ · = ·. 9: Designing the Drive System of a Fail-Safe Quick Valve Shut-Off 365.
