Mechanical Engineering QUESTION #2479
Question 1
In the vector loop method for position analysis of an RRR dyad with links \(L_2\) and \(L_3\), the vector closure equation projected onto the x-axis gives:
  • \(L_2\sin\phi_2 + L_3\sin\phi_3 = x_B - x_A\)
  • \(L_2\cos\phi_2 + L_3\cos\phi_3 = x_B - x_A\)✔️
  • \(L_2\cos\phi_2 - L_3\cos\phi_3 = x_B - x_A\)
  • \(L_2\phi_2 + L_3\phi_3 = x_B - x_A\)
Correct Answer Explanation
For the RRR dyad, the vector loop equation projected on x gives \(L_2\cos\phi_2 + L_3\cos\phi_3 = x_B - x_A\) and on y gives \(L_2\sin\phi_2 + L_3\sin\phi_3 = y_B - y_A\).
