Step 1: Identify the forces and their distances from the pivot. For a beam to be balanced, the sum of the clockwise moments about the pivot must equal the sum of the anticlockwise moments about the pivot. • The force on the left side is 9 N at a distance of 4 m from the pivot. This creates an anticlockwise moment. • The force on the right side is 4 N at an unknown distance d from the pivot. This creates a clockwise moment. Step 2: Write the equation for the principle of moments. The moment is calculated as Force × Distance. For balance: Anticlockwise Moment = Clockwise Moment F_1 × d_1 = F_2 × d_2 Step 3: Substitute the given values into the equation. 9 N × 4 m = 4 N × d Step 4: Solve for d. 36 Nm = 4 N × d d = 36 Nm4 N d = 9 m The distance d is 9 m. 3 done, 2 left today. You're making progress.
