Part D - A tractor shovel
The tractor shovel shown (Figure 4) carries a 510 kg load that has its center of mass at H. The shovel's dimensions are: $a = 54.0$ mm, $b = 216$ mm, $c = 324$ mm, $d = 108$ mm, and $e = 378$ mm. Find the reaction force at E. Assume that the positive direction of the $z$ and $y$ axes is to the right and upward, respectively.
Enter the Cartesian components of the reaction force at E separated by a comma. Express your answers in newtons to three significant figures.
$E_z$, $E_y$ =
