Question:

What is the fundamental frequency of a 1.70 m -long aluminum rod? The speed of sound in aluminum is 6420 m/s.?

A longitudinal standing wave can be created in a long, thin aluminum rod by stroking the rod with very dry fingersThis is often done as a physics demonstration, creating a high-pitched, very annoying whineFrom a wave perspective, the standing wave is equivalent to a sound standing wave in an open-open tubeIn particular, both ends of the rod are anti-nodes(Figure 1)

Answer:

Fig1 is missng but I'm guessing it's similar to the one in the link below (though the link is for an open pipe, not a rod)In that case, the rod's length is λ/2, so λ 2 x 1.70 3.40m f v/λ 6420/3.40 1890Hz to 3 sigfigs.
sounds like your not eating properlychange your meal plan i dont have a high fiber diet i mostly stay away from carbohydrates.
Your body will adjust but it may take timeGas-x, beano, mylanta or other such drugs will help with the pressureBe sure to read the labelsSome meds, like rolaids, even have calcium and are good for you.
Yes, that's a common result of high fiber diets - you're never told that high fiber diets can slow digestion to the point that the contents of your bowels begin to fermentThere are days when, being on a high-fiber diet myself, I produce enough gas to float the Hindenberg all over againI've tried Gas-x and a couple other such over-the-counter remedies and found they don't helpExercise, on the other hand, particularly taking a brisk half-hour walk, often does get the gas moving along so I can expel it more quicklyJust don't stand downwind when I do expel it - my toots can be classed as a weapon - a WMD!
i know a way to get rid of gas
