Torque is not power/time. Power has the units of energy/time. Energy units and torque units are nearly identical.

It’s unfortunate that pound-feet (i.e. torque) does not list the moment arm unit first. foot-pounds would make more sense in terms of remembering RxF=T where order matters for cross products of vectors.

While (16,500 lb * 100 ft)/(1 min) = 50 hp, there is a problem with the truck pulling example.

Doing exactly that now. I completely failed at flux core wire feed welding. The MIG stuff I’ve put together is messy but holding strong.

I hear that. Our Formula SAE team had a Red Bull sponsorship. It was product only. We had a rule that it was only for use to keep us working in the shop. I believe we were long since out of it before competition came.

Hagerty seems to think a good 733i is worth $5,800 and an excellent one $12,300.  This one looks very good and asking $9,000 seems in the ball park. Do I want this? No, but someone might reasonably pay that much.

Not all races are wheel to wheel. Many, such as time trials (i.e. time attack), autocross, and others are point to point timed. So yes, cannonball is racing, and it’s on the street, therefore it is a form of street racing.

Preach, Bradley.

That is a splendid idea.

I want to see and EV with a real fording kit. Suspension and drivelines that accommodate real off road driving in an EV are well understood. Complete immersion is a different animal.

This Old House and its ilk just make me feel inadequate as a homeowner. They make it all look easy and come out looking fantastic. Meanwhile, my home projects, um, do not.

With a Ferrari, you can have the tow truck ride without any aftermarket modifications, right?

Minor edit;

Dubya had smart people around him that he actually listened to. I disagree strongly with a number of those influential people in that administration, but they were smart and organized.

In the logic of my post above, bigger wheels will take more energy to spin up to a given speed thus have more kinetic energy at speed. From that it’s possible to get a larger amount of energy back from them. The trouble is that both speeding up the wheels and slowing them down, even when using an energy recovery…

I shouldn’t have used the 2nd law of thermodynamics in my response above. It’s not a direct line from there to the energy loss issue in this case. Still, the entropy concept is pertinent here.

Your point on the aerodynamic assertion is actually a good one. It’s reasonable that the increased energy used when rollin’ on 22s (rather than 19" wheel set) is due to something other than aerodynamic effects. The translational inertia (mass) and rotational inertia (defined by mass distribution from the axis of…

There are lots of reasons big wheels can be worse. Some important ones are not listed in the article. Suspension compliance and the consequent grip limits on bumpy surfaces is one.

Fuel tax, sales tax, property tax, and vehicle registration fees paid by employees of each might not fully compensate for the impact these companies and others like them have on the area. People keep trying to limit the vehicle registration fee to only $30/vehicle/year. Fuel taxes are going down as a proportion of…

Confirmed. My commute across Seattle was cut in half last week. 60 min to go 10 miles on the bus went to a mere 30, including wait time for the bus to show up at the stop. It wend from standing room only to everyone has a seat on their own.
