The planar nature of the problem lends itself to Scalar Analysis. 2. Resolve the 900 N force into its x- and y-components. 3. Using Scalar Analysis, compute the moments due to the forces: Use the Principle of Moments for the 900 force (i.e. use its components). The 300 N force already has an easily identifiable perpendicular distance to A. Keep track of the senses of these moments. 4. Determine the sense of the 300 N m couple, and then add this to the moments found in step 3 to find a single resultant moment at A. 5. Sum the forces in x and y and then combine them into a single resultant force in the…
