Answer:
The resultant of given forces is .
Explanation:
The component method consists in summing each component of known vectors in rectangular form to get the resultant. That is:
Where:
– Resultant, measured in newtons.
– i-th x-Component, measured in newtons.
– i-th y-Component, measured in newtons.
We describe each known vector below:
, South:
, North of west:
, South of west:
, South of east:
We find the resultant by vectorial sum:
The resultant of given forces is .
