For the systems shown below, find mobility and speed relationships.1) For figure 1, gear #2 and ring #4 rotate about pin A. Find mobility and giveexpressions gear #3’s and ring’s angular velocities.2) For figure 2, gear #2 and arm #4 (arm AB) rotate about pin A. Gear #3 rotatesabout pin B. Find mobility and give expression of gear #3’s angular velocity.3) For figure 3, gear #2, arm #4 and ring #5 rotate about pin A. Gear #3 rotatesabout pin B. Find mobility and give expressions gear #3’s and ring’s angularvelocities.
