Problem 1 (40 points): Link 3 103 Link 4 -sin 7 = Wil+ in a cos cos sin Link 2 02 Link 1 The figure above shows a four-bar linkage. Given Ira1 = 3 in, Irel = 1 in, Iral = 3 in, 0 = 0, 0, = 90°, 0. = 90°. 1) Mark the direction of all four vectors (using arrows) according to four-bar linkage conventions. (8 pts) 2) Write the vector loop equation for position analysis. Using these equations to find Ir3 and 03. (16 pts) 3) Given d2 = 1 rad/s, what are the unknowns in the velocity analysis? (6 pts) List the velocity vector loop equations and solve for the unknowns. (10 pts)
