Question details

Q-8      The figure below shows a four-bar with the following dimensions: O2O4 = a1 = 100 mm, O2A = a2 = 150 mm, AB = a3 = 250 mm, O4B = a4 = 250 mm, AC = b1 = 300 mm, BC = b2 = 150 mm. The input rotational velocity is to be taken as ω12 = 4 rad/s (c.c.w.).

  1. Locate the instant center I13 and show the directions of ω13, and ω14.              [12 pts.]
  2. Measuring the relative distances with respect to instant centers I12, I13, I14, and I13 of points A, B, and C, and making use of the given information, including the input velocity, ω12, determine the magnitude of velocities ω13 and ω14 in rad/s.                               [24 pts.]

[Hint: I12I23* ω12 = I13I23* ω13 leads to the solution of ω13.]
