Unformatted text preview: Example – Velocity Diagram F 1 8 Given: Find: ω 2 = 1 rad s 7 vF E 6 D 5 A 2 ω2 6 B 3 C O2 1 4 O6 1 1 1 in = 1 in s 1. Put an observer at A attached to link 3 vA ω 3 × rC / A v C = v A + v C / A + ω 3 × rC / A vC ω3 = ω 3 × rC / A rC / A = 0 1 in = 1 in s 1.5 = 0.375 4 2. We can now find the velocity of B v B = v A + v B / A + ω 3 × rB / A ω 3 × rC / B vA 1 in = 1 in s vB ω 3 × rC / A = (0.375)(1.75) = 0.6563 0 3. Put an observer at B attached to link 5 v D = v B + v D / B + ω 5 × rD / B vB 4. Find the velocity of E vE = 1 in = 2 in s ω 5 × rD / B EO6 (6)(0.2) = 0.3 in s vD = 4 DO6 0 vD 5. Put an observer at E attached to link 7 v F = v E + v F / E + ω 7 × rF / E vE 0 1 in = 4 in s vF ω 7 × rF / E vF = 0.22 in s ...
