Practical Applications Of Physics

Tonight while refreshing my scotch glass I was reminded, rather pointedly, of the difference between Potential Energy (U) and Kinetic Energy (K), with corollaries relating to the Work/Energy Theorem. It so happenned that, in the course of transferring an ice cube from the tray to my glass in preparation for adding additional quantities of ethanol to bring the total level to an acceptable height, one of the cubes managed to evade my grasp. Under the acceleration of gravity, it's U-value diminished rapidly, being converted into K by the rapid loss of altitude from approximately 39" above the floor to the top of my large toe, located approximately .75 inches above the floor, minus minor losses due to air friction. There were also some losses from friction due to rotation, which brought the mass into an orientation which directed the surface of ultimate contact with the target surface such that, at the moment of elastic collision, the narrowest edge of the ice cube contacted the toe first, minimizing the contact area. This, of course, maximized the impulse associated with the energy transfer which occured on contact, resulting in a peak energy transfer to the bone just above the knuckle of the toe. The momentary, but excruciating pain which resulted is intuitively ocbvious to a casual observer, but for the quiz: (1) Determine the energy (in kWh) delivered to the toe, given that the dimensions of the cube are 1.8" x .75" x .95", the area of contact is approximately 1/8" x 1/4", the composition of the cube is essentially pure water, at approximately 65 lbs/cu. ft., and the acceleration of gravity is 7.138 x 1010 furlongs per fortnight2. Assume the elasticity of collision to be .80, and illustrate your answer with a free-body diagram. (2) Estimate (to the nearest ounce) the quantity of ethanol required to numb the resulting pain for 1 hour. Bonus Question: Given a generator heat rate of 9.6 mmBTU/MWh, how many cubic feet of natural gas would be required to generate this much energy? How many tons of carbon (in the form of CO2) would be emitted into the atmosphere in the process? Keep your notes, as this question may appear on the final exam.

- This usually easy. It of couse depends on one's level of pain (use pain chart) 1 = "hhhmm, what was that?" to 10 = "@#$%$%&&*%$#@#$%^&*^ dang that hurts". Then one's body weight, type, and overall health might be of consideration, for other varibles that will factor into the proper amount, how fast the ethanol will be absorbed, processed, and eliminated, within the hour or after the hour. Numbness is a little subjective as well. If your pain level was equal to say a 7, then we could start with 7 oz. (fluid) of 100 proof grain alcohol. Straight up I am sure that this amount would knock most people on their respective butts. If you weigh 200lbs., depending on the muscle to fat content (bones are extra), and are not classified as a alcoholic (that the above amount would just be getting him started), then one might divide by the ratio of lbs of muscle / lbs of fat. A ratio of about 10 to 1 is a fat content of about 10%, with counting bone, is more like 3 to 1 with out it. This goes to the absorbtion factor, burn rate, blood level, and blood/brain barrier passivity. For me I weigh 220lbs. and it takes about 1.5 Long Island Iced Teas. The alcohols used are 80 proof, except for the slash of mixer. It is a mix of 1 oz. ea, Vodka, Gin, Rum, Triple Sec, sweet and sour, and the cola is optional. After drinking 1.5 drinks, the pain in my feet from standing for two hours or more goes away and I feel happy.

According to my maths, you should be footless and have a big hole in the floor of your kitchen, and your ice cube spoiled as much CO2 as the 45000km emitted by my car last year. :doh:
How much CO2 is 45000Km? Is that a lot? :-D

I rarely drink whisky, but when I do it is normlly neat, occaisionally with water. The main problem with ice is the cold, it kills the taste, ruining the good stuff. Some of the real buffs drink whisky watered from the same source as the distillary uses, my palette isn't that subtle...

It so happenned that, in the course of transferring an ice cube from the tray to my glass in preparation for adding additional quantities of ethanol to bring the total level to an acceptable height, one of the cubes managed to evade my grasp. Under the acceleration of gravity, it's U-value diminished rapidly, being converted into K by the rapid loss of altitude from approximately 39" above the floor to the top of my large toe, located approximately .75 inches above the floor, minus minor losses due to air friction. There were also some losses from friction due to rotation, which brought the mass into an orientation which directed the surface of ultimate contact with the target surface such that, at the moment of elastic collision, the narrowest edge of the ice cube contacted the toe first, minimizing the contact area. This, of course, maximized the impulse associated with the energy transfer which occured on contact, resulting in a peak energy transfer to the bone just above the knuckle of the toe. The momentary, but excruciating pain which resulted is intuitively ocbvious to a casual observer, but for the quiz: (1) Determine the energy (in kWh) delivered to the toe, given that the dimensions of the cube are 1.8" x .75" x .95", the area of contact is approximately 1/8" x 1/4", the composition of the cube is essentially pure water, at approximately 65 lbs/cu. ft., and the acceleration of gravity is 7.138 x 1010 furlongs per fortnight2. Assume the elasticity of collision to be .80, and illustrate your answer with a free-body diagram. (2) Estimate (to the nearest ounce) the quantity of ethanol required to numb the resulting pain for 1 hour. Bonus Question: Given a generator heat rate of 9.6 mmBTU/MWh, how many cubic feet of natural gas would be required to generate this much energy? How many tons of carbon (in the form of CO2) would be emitted into the atmosphere in the process? Keep your notes, as this question may appear on the final exam.
Will Rogers never met me.
When our physics prof explained to us that carrying a bowling ball up a flight of stairs, then carrying it down again results in 0 change in energy levels, i.e. no work done, we decided that physics had no application in the real world.

lol... are you a neat freak, or do you do the two drops of water with an eye-dropper to break the surface tension?

It's just not done. Unless you only have a cheap knockoff at your disposal, and the only alternative would be a slightly fermented coconut fruit punch. Then the ice is the difference between "well, it was not bad, my lad, a bit cold maybe" and GAAAAH! WHAT ABOMINATION IS THAT?

I rarely drink whisky, but when I do it is normlly neat, occaisionally with water. The main problem with ice is the cold, it kills the taste, ruining the good stuff. Some of the real buffs drink whisky watered from the same source as the distillary uses, my palette isn't that subtle...

FTFY because you seem to be a distinguished gentleman and able to take that small hint as well-intended as it is.
