Problem $2$:

A force of $Pz=780N$ is exerted on control arm BC $,$ which is securely attached to the solid $30$ mm diameter shaft shown in the figure below. Dimensions of the assembly are $a=150mm$ and $b=120mm.$

$(2-$a$)$ Find the equivalent Moments $(M_x,M_y$ and $M_z)$ at point $H.$

$Mx=-112,400.My=-217,200,$ and $Mz=0$MPa

$Mx=-32,800,My=-130,300,$ and $Mz=210,000$MPa

$Mx=-93,600,My=-117,000,$ and $Mz=0$MPa

$Mx=-59,800,My=-210,000,$ and $Mz=1,000$MPa
