I am still in school so my experience is limited. We have Solidworks there and I like it. Making parts and assemblies is easy. I haven't done any more than that.
I just got an internship at Raytheon and they use Pro/E. Holy $h!t that is a confusing program to use. I took about 1.5 weeks worth of...
The reason for these questions is from a video I saw. Two engines were mounted on a boat. Both were 225hp engines. One was a 4-stroke and the other was a DI 2-stroke. The 2-stroke has a lot more low end torque.
The boat was a heavy boat. While running the 2-stroke the boat accelerates and gets...
There are several ways to increase lower end torque.
Increasing displacement and tuning it for lower end power.
A simple exhaust pipe mod.
Using fuel injection instead of a carburetor.
A 2-stroke engine vs a 4-stroke engine.
So I understand an engine with 200lb-ft of torque may have 300hp at 7878 RPM and the 300lb-ft engine will have 300hp at 5252 RPM.
This means with the same gearing the boat B will hit its power sooner and accelerate faster but top out sooner. Correct?
Maybe I am wrong about torque in this...
I don't understand that explanation. Why is it physically impossible?
Where did you come up with,
"Boat A's propeller spins at 3/2 the rpm of Boat B's at that operating point"?
I stated that they have the same gearing. Include same prop. Therefore both propellers must be spinning at the...
I have a question having to do with the affect of torque on a vehicle. I have 2 situations to make it easier to respond.
Case 1
There are two boats. Both are identical, identical in weight, drag, etc. Boat A and boat B have single 300hp outboard engines. Although boat A's engine makes...
