Internal Loadings

state of Stress at A:

Find the Internal Loadings and determine the state of stress at A$.$

$N=0kN,V=6kN,T=1\mathrm{.}8kNm,M=1\mathrm{.}8kNm$

${}_A=0$MPa,${}_A=15\mathrm{.}53-4\mathrm{.}21=11\mathrm{.}32$MPa

$I=2\mathrm{.}898({10}^{-6})m^4$

$J=5\mathrm{.}796({10}^{-6})m^4$

$Q_A=40\mathrm{.}667({10}^{-6})m^3$

$M_x=1\mathrm{.}8kNm$

$I_Z=6kN$
