Unlike the common V6 engine, Subaru engines contain pistons that are horizontally opposed (see Wikipedia for more info). Luckily for us, this also makes for an interesting dynamics problem! At the instant shown, the crank arm's angular velocity is waB = 2,000 rpm (rotating clockwise) and the angle 0 40° with respect to the horizontal. Length of bar AB is ri = 3 in. and the length of bar BD is r2 = 8 in. a) Clearly define coordinate systems for each link and write transformation arrays for each. b) Compute the velocity of point B in ft/s. Express your answer in rectangular coordinates. [Ans. to Check: 33.66 i – 40.11 j ft/sec] c) Determine the magnitude of the speed of the piston P in ft/s. Note: all answers should be positive since we only want to know the magnitude of the speed, not the direction (the piston can only move in the horizontal direction). [Ans. to Check: 43.6 ft/s]

The Wright Brothers designed an engine and propeller that would produce enough forward motion to lift a simple light airplane. The 3 meter diameter blade rotated at a constant 330 rotations per minute (RPM). How does the RPM of the tip of one blade compare to the RPM of the middle of the one blade (halfway towards the center of the propeller)? The RPM is twice as much. The RMP is the same. The RPM is half as much. The RPM is one quarter as much.
