If each link is considered as a uniform slender bar with weight density γ , determine the total kinetic energy of the system. Given: AB 2 rad s = a 3in = 0.5 lb in = b 4in = θ 45 deg = c 5in = Solution: ρ g = Guesses BC 1 rad s = CD 1 rad s = v Gx 1 in s = v Gy 1 in s = T 1lbf t = Given 0 ω AB 0 a 0 × 0 ω BC b 0 0 × + 0 ω CD c θ () c θ () 0 × + 0 = 0 ω AB
