Mnemonics for Strength

Mnemonics for Strength of Materials Stress = P/A

(NakakaStress ang Problema sa Asawa)

Stress(tangential) = ρD / 2t 

(si Rudy nung 20, tange pa)

Stress(longitudinal) = ρD / 4t 

(si Rudy at 40, lolo na)

ε = ΔL / L

(Everyday may Change in price sa Langis per Liter)

Stress = E ε 

(NakakaStress ang Evat Everyday)

δ = PL / AE

(Humaba ang Pasensya ni Lolo sa Alilang Eengot-engot)

δ(weight)  = L2 gρ / 2E

(Ang Bigatin na si Lot Lot ay GuRo ng 2nd  grade sa Elementary)

τMAX = T*r / J

(Tara Jay! Tara Tara Tara Jay!) Ja y!)  pwedeng kantahin to

J(Solid Shaft) = πD4 / 32

(Solid Precious Diamond, 4.32 Million) Hollowπ(D4 –  d   d 4)/32

θ = TL / GJ

(Owsss, talaga Jay?)

P = 2 π T n

(Patupi ng Tshirt Nanay)

τ(Approx)  = (16PR/ d 3π) (1 + d/4R)

(16 Pasaherong paRotonda, mga 3:14, basta 3AM dilim pa, may isang sumakay, dala’y apat na Rosas)

τ(Exact)  = (16PR/ d 3π) ((4m-1)/ (4m-4)+ 0.615/m)

δ = 64 P R 3 n / Gd 4

(16 Pasaherong paRotonda, saktong 3:14, basta 3AM dilim pa, “apat manong isang bata” “apat manong lahat matanda” “sobra ng dyis manong”)

T2 = (ωL/2)2 + H2

Draw right triangle, let Tension at support be hypotenuse.

H = ωL2 / d8

(Kuya dudung, WaLa ‘tong date)

S = L + 8d 2/3L –  32d   32d 4/5L3

(Si Lita, may walong d#$%, 3 maLaki, 32/4 is 8, if 3 maLaki, 5 hindi) censored 

T=ωy

(Toy)

S2 = y2 –  c  c2

Draw right triangle, let height of the support be hypotenuse.

x = c ln ((S + y) / c)

(Ex ni dudung, si Ellen C. Sy)

T2 = (ωS)2 + H2

Draw right triangle, let Tension at support be hypotenuse. Similar to parabolic, just change L/2 to S.
