Question

A rod ABC rotating at 20rpm about a vertical axis
through point A supports a 400N ball at its lower end. It
is fixed in position by the rod BD as shown in the figure.
Neglecting the weights of rods AC and BD, compute the
force P in rod BD. Identify if this force is in tension or
compression. At what rpm will this force be zero? Draw
FBD of the rod AC during the motion of the system.
