I.) There are 3 Cartesian vectors A, B, and C, which can be
expressed in terms of their components
A=3i + 5j – 7k
B= 3i + 9j
C= 7i - 4j + 6k
Determine the (a) Dot Product (A*B) and (b) Cross Product (A X
C).
II) Shown in the picture, the supported beam has a
load. Determine the reactions at the support A
