1. The problem statement, all variables and given/known data In a four bar linkage r0=30mm, r1=10mm, r2=35mm, r3=20mm and theta1=45 degrees. Calculate theta2, theta3, Vc, W2, and W3 assuming that W1=30 rad/s ccw. 2. Relevant equations R1*costheta1 + R2*costheta2 - R3*costheta3 - R0*costheta0 = 0 (3-x) R1*sintheta1 + R2*sintheta2 - R3*sintheta3 - R0*sintheta0 = 0 3. The attempt at a solution I wasn't sure about this equation from the start since I think it relies on knowing two angles and I only know one. I first plugged in for 10*cos45+35*costheta2-20*costheta3-30*costheta0 10*sin45+35*sintheta2-20*sintheta3-30*sintheta0 equals 5.252+35*costheta2-20*costheta3-30*costheta0 8.509+35*sintheta2-20*sintheta3-30*sintheta0 and I'm already wondering what I should do from here.
