In the two-cylinder air compressor shown, the connecting rods BD and BE are each 190mm long and crank AB rotates about the fixed point A with a constant angular velocity of 1500 rpm clockwise. All questions below are for the instant shown in the diagram (a) Determine the velocity vector of point B (b) Determine the acceleration vector of point B (c) Determine the angular velocity of bar DB (d) Determine the angular velocity of bar BE (e) If you haven’t already, describe/draw where the instantaneous center of rotation for bar BE (f) If you haven’t already, describe/draw where the instantaneous center of rotation for bar DB (g) Determine the acceleration of piston D (h) Determine the acceleration of piston E (i) What if the crank AB had some angular acceleration? No need to solve anything, just describe what would change Rods DB and BE are pinned to the crank AB as shown below

Use the diagram and position vectors as a function of time from the previous problem. If aircraft A has a mass of 100,000 Kg and aircraft B has a mass of 200,000 Kg And both aircraft collide and stick to each other (so they move with the same velocity vector after the collision, an inelastic collision) (a) Determine the velocity vector of the aircraft stuck together after the collision (b) If the aircraft are 10,000m high when they collide how long before they hit the ground? (c) Assuming the x and y velocity found in part (a) remains constant as the aircraft fall, how far in the x and y directions do the aircraft travel from when they collided, to when they hit the ground (d) When they hit the ground and their velocity goes to zero, their kinetic energy suddenly goes to zero, where did that energy go??
