Unformatted text preview: established, we assume precision point not at the top of the cradle as shown in Figure P8.12, but directly underneath the ones pictured at the base of the cradle (so that, for example, P1 = (0, 0) is on the trailer bed). We take γ2 = 13◦ , γ3 = 0◦ . As for the displacement vectors, we pick δ2 = −8.08 + 4i, δ3 = −14.92 − 3.1i. As for the angles φj , ψj , j = 2, 3, we pick the values show below in the Matlab session below >> ph=[77,155]; ps=[71,141]; >> gam=[13,-1]; >> d=[-8+4*i, -15-3*i]; >> zout=motion1ad3(d,gam,ph,ps) zout = -2.9735 - 0.7411i 7.1407 + 3.1797i -3.1674 + 0.2208i 6.9468 + 4.1416i -2.4811 - 2.5296i 0.6863 - 2.7504i we also obtain the plots 6 6 6 4 4 4 2 2 2 0 0 0 -2 -2 -2 -10 -5 0 5 -10 -5 0 5 -10 -5 0 5...
