2. The mechanism used in a marine engine consists of a crank AB and two connecting rods BC and BD. If piston C is moving down on the inclined plane (at 45 degree) with 2 m/s, determine angular velocities of links AB & BD at the instant shown and linear velocity of piston at D. For full credit separate kinematic diagrams for each member to be drawn, angular velocities & velocities vectors to be clearly labeled on kinematic diagrams. Note: For link BC for full credit IC method is to be used. For link BD for full credit scalar analysis is to be used. Solutions without proper diagrams will be graded zero. Do not use Cartesians vectors i,j,k (it was not covered in class). If using Cartesians vectors for solution, grade will be zero. (10 marks) D 45 1 0.4 m 60 30 45 0.4 m B 0.2 m
