Question 1
A uniform beam of length 6 m has a mass of 60 kg and is balanced on a pivot at its center. If a 40 N weight is placed 2 m to the left of the pivot, what weight must be placed at the right of the pivot to maintain equilibrium?
💡 Hint: Use the principle of moments to set up the equation.
Question 2
A seesaw has a 25 kg kid sitting at one end (4 m from the pivot), and a 30 kg kid sitting 2 m from the pivot on the other side. Is the seesaw balanced?
💡 Hint: Find the moments created by each child and compare.
