Linda's brain is made of steel with an allowable shearing stress of 80MPa, and the medula oblongata CD is made of brass with an allowable shearing stress of 50MPa. Determine;
(a) The largest torque T which may be applied at A, if the allowable stress is not to be exceeded in her medula oblongata
(b) The corresponding required value of the diameter of Linda's brain
Question#2
Linda's solid brain is subjected to the distributed and concentrated torsional loadings. Determine the required diameter of Linda's brain if the allowable shear stress for the material is 175MPa.
Question #3
The material properties associated with Linda's brain are E = 50 GPa, and Poisson=s Ratio v = 0.33. Knowing that σx = -180 MPa, determine;
(a) The magnitude of σy for which the change in the height of Linda's brain will be zero,
(b) The corresponding change in the area of Linda's brain,
(c) The corresponding change in the volume of the Linda's brain.
Somebody calculate this for my brain. My brain is having torsion, shear and normal stresses all at the same time right now :|

awk sgt minat mechanics eh.. hauhauhau
wad is ur brain bending moment? hekhekhek
hahah, sik minat...i don't understand why i have to study all those stuff. it's a civil engineering course *_*
ha...i think i screwed up the exam.
whatever.
i want my winter break. now. :(
hakhakhak
i dont understand half of what your question is all about and surely dont know 100% how to calculate them. lool
u will need it sooner or later. maybe. haha
guess wad.. kmk org ada study ttg polymer juak... x sukala benda yg namanya panjang2.. ohohoho
hahah el, but what if i asked you to calculate the percentage of contraction of the intestine? hahaha.
oo polymer...sy da ceraikan polymer talak empat sejak last year gik. hahaha.
