A cylindrical rod of steel (E = 207 GPa, 30 * 106 psi) having a yield strength of 310 MPa (45,000 psi) is to be subjected to a l
sineoko [7]

Answer:9.477 mm

Step-by-step explanation:

Given

E=207 GPa

Yield Strength(s_{yt}) 310 MPa

load (P)=11,100 N

length of rod(L)=500 mm

\Delta L=0.38 mm

we know \Delta L is given by

\Delta =\frac{PL}{AE}

where A= cross-section

A=\frac{11100\times 500}{0.38\times 207\times 10^9}

A=70.556\times 10^{-6} m^2

A=\frac{\pi d^2}{2}=70.556\times 10^{-6} m^2

d=9.477\times 10^{-3} m

d=9.477 mm

then 200 marbles would requrie    .06 l/marble x 200 marbles = 12 liters

so he would only need  26-12= 14 liters of water to fill the tank !
