FORT WAYNE, Ind. (WANE) -- Police currently have a warrant for the arrest of Jeremiah Jones who was charged Thursday with battery and criminal recklessness after he allegedly threw an adjustable wrench, or channel locks, at a four-year-old girl in February.

According to court documents an argument between Jones and his father, James, over tools became physical when he threw the tool at his dad, but hit the girl instead.

James Jones told police his wife and granddaughter got in between the two to separate them while they were arguing.  When the argument ended, James said he turned away from Jeremiah until he heard his wife say, "Jeremy, No!" James said as he turned back around, Jeremiah threw the tool. 

The girl was initially take to Dupont Hospital, but then transferred to Lutheran Hospital where she underwent surgery on her head.  She was then put into an induced coma.

The surgery removed an egg size piece of her brain and a titanium mesh was placed over the hole in her skull.  The girl also suffered a collapsed lung and had to be put on a ventilator.

During an interview with police, court documents said Jones initially said he threw the channel locks at his father's feet and did not throw them with any type of force that would cause injury to anyone. He eventually admitted when he threw the tool, he did hit the girl.

According to the Allen County Sheriff, Jones has not been arrested yet.
 

Many imported vehicles can amost be stripped and rebuilt with only three sizes: 8, 10, and 12mm. The Pack Wrench combines all three socket sizes into a T-style wrench that’s small enough to fit into a fannypack, but it’s so handy that you’ll find yourself using it in the garage and pits, too. Motorcyclist said “Barely larger than the palm of your hand, this tool should be in our traveling kit. Heck, at .95, buy two and keep one in the shop.” [December, 2001)

Feature and Specification :

• Compact T-Handle Wrench with 8, 10, and 12mm Sockets
• Polished Chrome Finish

Mountz Inc. introduces a new cam-over torque wrench designed with a "Through Hole Spindle" for Pin Fastening applications, which cannot be gripped in the conventional manner. Fasteners such as HI-LITE®, AERO-LITE® and VERI-LITE®, are threaded pins with a close tolerance design intended for applications where aerodynamic and precision fastening is required. These 'blind' fasteners are increasingly being used in the aerospace industry.

Accurate tightening of blind fasteners can be achieved with this new innovative torque wrench. The "Through Hole Spindle" design of the wrench makes it simple for the operator to use and ensures precision torque control. The "Through Hole Spindle"  torque wrench operates by having a hexagon key is passed down the axis of the square drive shaft to hold a fastener in position while its securing nut is tightened by an operator using the torque wrench.

The "Through Hole Spindle" torque wrench is a pre-set torque wrench that's ideal for maintenance and production applications where over-torque conditions are not tolerated. Built with a cam-over design, the accurate torque wrench prevents a fastener or bolt from being over-torqued. The design action of the cam-over torque wrench is such that when the tool reaches its pre-set torque value the mechanism disengages from the drive thus limiting the torque applied. Designed for variety of industries like aerospace, automotive, electronics, energy, medical, and packaging, the Mountz Inc. cam-over torque wrench ensures proper torque control.

A pre-set torque wrench is similar to a person setting an alarm clock to signal the achievement of a selected time. The torque wrench is pre-set to the required torque value of the application and then the tool signals the operator when torque is achieved.

Inside the cam-over torque wrench, a precision radial ball clutch "slips-free" when the pre-set torque is reached preventing the fastener from being over-torqued. The use of a cam-over torque wrench takes the operator influence out of the torque equation and offers more accurate and repeatable results than a standard 'click' type wrench. A click wrench typically breaks about 3 degrees after set torque is reached and then becomes positive. If the operator continues to pull on the click wrench, he or she can over tighten the fastener.

The cam-over torque wrench features a tamper-proof internal adjustment. There is no external adjustment scale so the wrench must be preset using a torque analyzer. Crafted with a soft texture grip, Mountz offers various "Through Hole Spindle"  torque wrench models covering a torque range from 0.8 foot-pounds up to 90 foot-pounds.

Controlling torque is essential for companies to ensure their product's quality, safety and reliability isn't compromised. The failure of a three-cent fastener that isn't properly tightened can lead to catastrophic or latent failures. Fasteners that are insufficiently torqued can vibrate loose and excessive torque can strip threaded fasteners. Using a quality torque wrench has become increasingly important for many companies to ensure that proper torque is being applied and maintains gauge requirements associated with the ISO 9001 Quality Standard.

6.2: Kinetic Energy and the Work Energy Theorem

This is a short section, but understanding it is very important to understanding reality.

We established last time that work is force times distance. So, when you slide along the floor in your socks and nothing else because your wife is away this week, work is equal to the force of friction at any given point in your slide, times the distance you go. Work in this case is negative, in that the force goes in the direction opposite the direction of motion.

Now, we get to an even bigger concept: kinetic energy.

Say you’re in space and you want to kill your fellow astronaut because looking into the void of space opened your eyes to the void in your soul and now life seems like a pathetic yet heavy burden. You say “hey, let’s go for a spacewalk.” He says “sure, buddy!” You grab a wrench.

When you get out, you hurl the wrench at him. It smacks him in the chest. He goes flying into the vast starry oblivion. But, let’s look at that in physics terms.

First, you accelerate the wrench. You do this by applying force to it with your arm. The wrench moves through space with a force on it, so we say it does a certain amount of work. As it leaves your hand, it ceases accelerating. However, clearly its behavior has been altered by the force you put on it. If you’d put a different force on it or applied that force for a shorter distance, it’d have a different velocity.

Second, the wrench flies in a straight line through space at the other astronaut. Intuitively, you know that for a given wrench, higher speed means it’ll shove the other astronaut harder. This is because you’ve conferred a quality called Kinetic Energy onto the wrench.

Third, the wrench smacks into the astronaut. The wrench decelerates, so you know a force is acting on it. Namely, it’s the force of the astronaut’s body. So, there’s also a force on the astronaut’s body, which shoves him off into space. The wrench does work on the astronaut.

Fourth, the astronaut flies off into space with a velocity determined by how much work the wrench did on him.

You can see a nice quality here emerging – work confers kinetic energy on the object, which then can do work on another object, which then acquires kinetic energy. Cool!

And, you should also see there’s a sort of equivalence between the work you do on the wrench and the new kinetic energy the wrench has.

Let’s do the math.

The book provides a derivation for you that spits out:

That is, work is given by the change in the quantity, one half mass times energy squared.

You’ll note that for an object that starts at rest (like our wrench), one of those terms disappears. The remaining quantity is killed Kinetic Energy:

So, you can see then that there is a clear relation between work and energy given by:

Work equals change in kinetic energy.

Here, the book gives a brief discussion of units of energy. For macroscopic stuff, energy is typically given in Joules. Joules are a very nice unit which I wish we used more in regular life. Instead we get our power bills in “killowatt-hours,” which is like saying “energy divided by time times time.” But, I digress…

Now, the important thing is that you have a conceptual understanding of kinetic energy. Here’s how I like to think of it:

We’ve talked about force as the tendency to change velocity. That is, something happens to an object to tell that object “CHANGE YOUR MOTION!” That is, force is information given to an object about how to move.

Kinetic energy can be thought of us the quality of the object that has been made to move. That is, although it no longer has a force applied to it, it carries that information along, and can deliver it to other objects, just as the wrench did in the example above.

This is the case because of conservation of energy, which we’ve discussed. Energy is conferred to an object. That object moves as a result. When that object smacks some other object, it transfers energy out.

At the end, the book makes a point of noting that we are of course working with idealizations. Conservation of energy holds, but real life systems are more complex than two particles interacting. Imagine, for example if you threw the wrench poorly and hit the astronaut’s hand. The same amount of energy might be transferred to him, but he’d spin around instead of flying off. And the really freaky part is you could get that energy back out by letting the spinning astronaut smack the wrench. So, although the information in 6.2 is very good, so far you’ve only learned how it works in the simple case where two idealized particles smack each other.

But soon… soon your physics might will grow…
