Question:

$218$

Give $A,B,$ and C equal to the last $3$ figures of your student ID$,$ respectively $($ABC $),$ solve the problem below.

Give the followings for the values of stresses and angle:

$,=,(50+z_1)$ deg. $52$

${}_{yy},=(80+),k\frac{N}{m^2}81k\frac{N}{m^2}$

${}_{},=(150+){}^{8}k\frac{N}{m^2}k88k\frac{N}{m^2}$

$|{}_{xy}|=|{}_{yx}|=30,k\frac{N}{m^2}30k\frac{N}{m^2}$

Use two significant digits in your calculation. For a soil element given below, by means of Mohr's circle of stress, determine:

a$)$ Major and minor principal stresses.

${}_1,{}_3$

b$)$ Normal and shear stresses acting on the plane AB $.$

Note: Use at least three decimals in your calculations, e$.$g$.,0\mathrm{.}000.$
