Practice Questions

Question 1

For a planar mechanism with 6 links and 7 single‐degree‐of‐freedom joints, what is the mechanism’s mobility according to Gruebler’s criterion?

Question 2

In a four‐bar linkage with link lengths s=3, l=9, p=5, and q=6, which condition applies according to Grashof’s law, and what type of motion does the linkage exhibit?

Question 3

A rigid link in a mechanism rotates about a fixed pivot with angular velocity ω = 4.0 rad/s. If a point on the link is 0.25 m from the pivot, what is the linear velocity of that point?

Question 4

In the following compound gear train: Gear A (20 teeth) drives Gear B (40 teeth) on the same shaft as Gear C (10 teeth), which in turn drives Gear D (50 teeth), what is the overall speed ratio ω_D/ω_A?

Question 5

In kinematic notation RRRSR for a planar chain, what does 'S' represent?
