PRACTICE$-$AT$-$HOME PROBLEM $1$

Rods $AB,BC,$ and $BD$ are all made out of the sam

material while the diameter of $AB$ is different from I

and $BD.$ Determine the displacement of point $A.BC$

$A_{BD}=0\mathrm{.}001m^2$

$A_{BC}=0\mathrm{.}001m^2$

$E=120$GPa

$15000$ N

Answer:

Displacement of Point $A=0\mathrm{.}05383mm$
