Slope and Deflection

The slope in a deflected beam is described as an angle in radians made by the tangent of the section with the original axis of the beam. The deflection at any point on the axis of the beam is defined as the lateral displacement of the point before and after loading.

Question

Area of the down sprue??

A 200 mm long down sprue has an area of
cross-section of 650 mm² where the pouring
basin meets the down sprue (i.e. at the
beginning of the down sprue). A constant head
of molten metal is maintained by the pouring
basin. The molten metal flow rate is 6.5 x 105
mm3/s. Considering the end of down sprue to
be open to atmosphere and acceleration due
to gravity of 104 mm/s?, the area of the down
sprue in mm² at its end (avoiding
