Hello,
I am trying to analyze the forces on a chain and sprocket system. Specifically the force on each tooth that is engaged with the chain rollers on a driven sprocket. Here are a couple links on the topic, however niether of which provide a derivation or sample calcs on how they got their...

Aight so I started from square 1 again and here's all the needed requirements-
-Transport car
-low speed
-minimum range 5 miles
-minimum top speed 5mph
-loaded minimum top speed 3
-unloaded weight=1000lB
-max loaded weight 1500lB
-must be able to climb 30 degree gradient
-So I re did all...
Only calculated rolling resistance since minimum top speed needed is only 4 mph. Which the power req. at the wheels to do this is only 6.5 kW and the energy req. for that speed and required range was 10.4 kWh. Thanks for the helpful reply. My next question is how would you determine the gear...
So for a school project I got to design an electric car that can meet minimum range and top speed requirements for how heavy it is. I have calculated the amount of power needed(kW) for its heaviest load situation to reach the min speed and range, along with the necessary energy(kWh) required...
I am not talking about the mechanics of them, I am talking about what factors influence how much fuel they pump in a given system(EFI return style) at a given time. What do numbers such as maximum pressure and free flow rate mean? Can you have a pump that is too powerful for a system like say...
So let me see if i can now explain how the fuel system works now with the pressure regulator mounted at the end/after the fuel rail. Fuel is pumped out of the pump at a certain pressure through the fuel lines and up into the fuel rail all the way to the pressure regulator. The fuel in the rail...
When designing the fuel plumbing for an efi system, do pressure drops in the fuel lines need to be considered when there is a pressure regulator? If so why? Been reading up a lot on plumbing design lately about how the goal is to minimize restrictions in the lines which ultimately cause...
Hello, I am working on a automotive fuel system for a school project and one of the problems is not enough fuel at higher rpm's. Would a larger fuel line help this problem? The pump has been determined that it should be powerful enough for the necessary supply and wondering if there can be...
