A streamlined design engine refers to the aerodynamic shape of a vehicle, which is optimized using wind-tunnel testing to reduce air resistance. This design minimizes energy loss due to frictional forces, allowing more fuel energy to be utilized effectively. Recent advancements in automotive design, influenced by racing technologies, focus on enhancing airflow and reducing vehicle weight by simplifying components. Additionally, the term "streamlined" can apply to improving overall efficiency in various processes, not just aerodynamics. Understanding these principles can significantly enhance fuel economy in vehicles.

I Have A Puzzling Question!

CAN SOMEONE PLEASE TELL ME WHAT A STREAMLINED DESIGN ENGINE IS AND HOW IT IMPROVES THE FUEL ECONOMY.

Thanks

I'm assuming you are in the "energy" chapter of your texbook?

"Streamline designed" is referring to the shape of the car (not the engine) which was designed with the use of a wind-tunnel. The result is a reduction of air resistance on the car. This means less of the car's energy is lost to "fricitonal" forces. So therefore more of the car's fuel energy remains as ... (you know)
 
Thanks a lot. That helped so much.
 
Ahem it might very well be respective of recent design improvements that are following racing technologies inasmuch as the intake manifolds are polished to un-restrict airflow, many design features are to improve (by reduction) the motors weight, reduce the number of components (other then the computerized pieces that have been added) as to make the processes of assembly, design, (itself) and repair, more efficient and accessable...

Streamlined doesn't just refer to airflow principals it is and can be used as a general term for making processes smoother, making operation smoother, that kinda thing...
 
The book claims the answer is that all the magnitudes are the same because "the gravitational force on the penguin is the same". I'm having trouble understanding this. I thought the buoyant force was equal to the weight of the fluid displaced. Weight depends on mass which depends on density. Therefore, due to the differing densities the buoyant force will be different in each case? Is this incorrect?
