A rectangular parallelepiped carries three forces shown in fig. Reduce the force system to a resultant force applied at the origin and a moment around origin.

NOTE: We have to replace by a force and a couple. It means we need to find the Resultant and the total moment about origin.

$R= 484i + 350j -103k N \\ M = M1 + M2 + M3$

= $[ i(-412) –j(515) +k(686)] + [ i(0) –j(0) +k(-500)] +[ i(750) –j(937.5) +k(0)] \\ \therefore M= 338i -1452.5j + 186k Nm $
