Question

 Replace the loading by an equivalent resultant force and couple moment at point O. Suppose that Fi = [8i -3k) kN and F2 = {-3i+3j - 2k} kN. (Figure 1)

 Part A

 Determine the resultant force.

 Part B

 Determine the equivalent resultant couple moment about point O.

Answer 1

Solution:

Given that:

Replace the loading by an equivalent resulant force and couple moment at point O

F1={8I-3K} KN

F2={-3I+3J-2K} KN
