So I went to the bathroom today and say some brownish red stuffIm 14 years old so I knew that it would have to happen soonI skipped track practice today because I didn't know what to doI also have really bad crampsI have winter track outside tomorrow so I have to wear running pantsShould I wear a pad or try a tampon? Also, I feel so discussingOh, also any other advise would really help!
Pay attention to the unitsStress is in units of load per unit area (lbs per sq in {psi} or N per sq m)Strain is technically unit-less but the real units are length per unit length (inch per in or m per m)Modulus Of Elasticity is the slope of the elastic portion of the stress strain curve so it is in units of stress per unit strain (psi per inch per inch or N per sq m per meter per m) or same units as stress (since strain is unit-less)Hope this helps.
a)Tensile stress (Force/Area)(20E3/pi150^2.25) 44.21N/mm^2 b)Elastic strain (Change in dimension/original dimension) (95E-6/150E-3) 0.0006 c)Modulus of Elasticity Stress/Strain 44.21/0.0006 0.6980E5N/mm^2
Talk to your mom and the best thing to do since you just started is wear padsDon't be alarmed if your period cycle is irregularMine still is and i have had mine for 5 months nowThey are a painAnd the worst part is the changing the pads and all of the crampsAnd you can still wear pads for a sport except swimmingI wore a pad for the football game I cheered at and my volleyball game that I played in blood freeAnd I had nothing to worry about but my gamesAnd if you go swimming wear a tampon and if you wear a tampon you have to change it 3-4 hours or I read from a site that you can get tss (or something like that) I got mine in July and I couldn't wear any tampons so I went to the pool and had my pad and undwear on and I wore shorts and my bathing suit top(no biggy.) And I only wear pads because I am scared to talk about tamponsAnd don't forget to mark an x on the calender everytime you get it and to see how many days the cycle is(don't worry if it is a different amount of days it might be irregular.)
