History Flat tire & no jack

Double Cola was so named because it was twice the size of Coke Cola, Cole was in a small bottle and a product out of Tennessee. HRP

It appears that in this time period the local triple AAA used mules to extract stuck cars. HRP

 

How about a little flat tire humor ?

 

Remind me to toss a 4x4 and a chunk of 6x6 in the back of my 61 F100.

Time to get prepared.

 

Well, being a Chevy sedan, I would have just left that Stovebolt in the pasture. JUST KIDDIN' ! JUST KIDDIN' !

 

If you notice they're pulling it INTO the creek. They probably figured the old Chevy had enough wood in it to float it home

 

I know you're joking, and if it is reversed it's irrelevant, but ...

I was looking at the bottom right margin and wondering if the picture is reversed and if that writing is a clue.

 

By the way, both you guys are basically right. But don't confuse Potential Energy with Kinetic Energy.
Both a bicycle pedal arm and a crankshaft throw act as a lever in a rotational system...and gives a mechanical advanage . In layman's terms, The force required to move that lever depends on the length of the lever from the center (fulcrum) and the mass being moved...that's Potential Energy.
Unfortunately, the Potential Energy can only be applied to the lever for less than 180 degrees of the rotation and then it becomes rotating mass.
Kinetic Energy is what keeps the rotation going for the other 180 degrees...Momentum and Centrifugal Force. The greater the mass, the more Kinetic Energy created, but the more Potential Energy required to get it moving. It's a balance...a great example of applied Kinetic Energy are those old stationary engine flywheels

 

Thanks, Hotrodjack, for explaining the difference in those two energies! I always had trouble distinguishing between the two! You made it very simple.

Yeah , seems theres a commercial of some wimpy kid calling his mom because he had a flat and he/she talks about some road side service . Hell, I put on a water pump on the side of the road once in Altana on 75 anmd these kids cant ( or want ) change a tire. Taught both my kids early how to change a tire, Check oil, What to do if car over heats , all the essential stuff not requiring a cell phone.

 

Glad I could help. The easiest way to remember is one is associated with work being done and the other (usually) is associated with the work already done.

Whewwww, That's enough "left brain" (logical) thinking for one day...I'm going back to my "right brain" (creative) for the rest of the day...it's more fun

A frozen moment of time.

 

I've never learned to change a tire. I know how to switch a wheel that has a tire on it with air in it for a wheel that has a flat tire.

 

Did you just draw that?!

Man, I hate to say it, but I think you misunderstand potential energy.

Kinetic energy is mass moving, such as a car driving.

Potential energy is not moving but has the potential to release energy. Maybe the best way to think of potential energy is water held back by a dam at a height. Let that water go and it is able to ~automatically~ change into kinetic energy. That energy can be harnessed to power a turbine to produce electricity. Or an engine lifted off the ground by a chain hoist. If it drops, that's a bit of energy.

I'm thinking it'd be cool if you explored these through your artwork.

 

Well, yes and no. Those are 2 example of gravitational potential energy which consequently dosen't require "work" to achieve . In a mechanical/elastic potential energy, there is work involved in creating the potential energy. For example, a bow and arrow when the bow is drawn tight, that is stored potential energy...but it took work (mechanical force) to achieve it. In it's prone relaxed position, it contains no energy, until work is added.
I believe the bicycle pedal/sprocket is the same situation (I could be wrong). In itself it has no potential energy, but when tension is applied to the pedal with work (mechanical force) to get rotation of the sprocket, chain, wheel, it also is the release of Potential energy...much like letting go of the arrow, only much slower. Again, I could be off on this

 

Oh yeah, I almost forgot...The artwork is an old "Self Portrait" I did back in college. But, I've done a ton of automotive artwork over the years and I post some of it almost every week on the "Friday Art Show" thread here on the HAMB.

 

A key point is potential energy is not moving. Voltage is potential electrical energy. Gasoline is potential chemical energy. They're not realized until they move. I don't think a lever (bike crank, engine crank throw) should be considered potential energy. Someone pedaling is applying force; it's not stored then released in the legs or cranks. So, storage and release are also key points.

 

Yeah, I think you may be right. I was assuming that having to do work/use force to achieve the Potential Energy was/could be formulated into the equation for Elastic/Mechanical potential energy. Nope...that math doesn't exist. Everything points to, and up to the moment BEFORE release. I concede
