Determine the magnitude,direction and resultant coplanar concurrent force.
Explanation of Solution
Given:
Concept Used:
Parallelogram law of forces. Constructing a parallelogram of OABC with AB is parallel to side OC and represents of
Calculation:
Angle AOC and Angle OAB are supplementary
By applying the law of cosine rule R can be determined
By taking the law of sine rule
Conclusion:
Therefore, the magnitude and resultant coplanar as follows
