Question

3 see below a free - body diagrams a situation. the net force is known. however, the magnitudes of a few of the individual forces are not known. analyze the situation and determine the magnitude of the unknown forces.

Explanation:

Step1: Analyze vertical forces

Since \(F_{net} = 0N\), for vertical forces: \(B-200N = 0\).

Step2: Solve for \(B\)

\(B=200N\) (upward to balance the \(200N\) downward force).

Step3: Analyze horizontal forces

For horizontal forces: \(A - 50N=0\).

Step4: Solve for \(A\)

\(A = 50N\) (leftward to balance the \(50N\) rightward force).

Answer:

B. \(200N\), Up; C. \(50N\), Left
