Q1) The Linkage in the Figure below has link 1 at -33 degrees and link 2 at 57° in the global XY coordinate system. Use the instant center technique to Find $\omega_4$, $V_A$ and $V_B$ in the global coordinate X-Y system for the position shown if $\omega_2 = 20$ rad/sec. For $a_2$=0, Find the angular acceleration of the link 3 and 4.

Instant Answer

Solved by Expert Ethan Deweese

Step 1

The instant center is the point where the two links would intersect if they were extended. For link 1: - The instant center is located at the intersection of the perpendicular bisectors of link 1 and the line connecting the origin (O) and point B. - Since link 1 Show more…
