Plate ACD Angle [20 pts] -- Note that the same
system will be used on the following two problems.
The heavy metal plate ACD has the dimensions
shown. In an attempt to tilt plate ACD, by rotating it
around its base AC, you plan to pull on cable DB
with a force of $\vec{F_{DB}} = (1.77, 1.549, -1.106)$ kN.
What is angle $\theta$ between force $\vec{F_{DB}}$ and the line
DE on the face of the plate?
