The sketch shows a painter's scaffold in mechanical equilibrium. The person in the middle weighs $500 \mathrm{N},$ and the tensions in each rope are 400 $\mathrm{N}$ . What is the weight of the scaffold?
The sketch shows a painter's scaffold in mechanical equilibrium. The person in the middle weighs $250 \mathrm{~N}$, and the tensions in each rope are $200 \mathrm{~N}$. What is the weight of the scaffold?
The sketch shows a painter's scaffold in mechanical equilibrium. The person in the middle weighs 500 N, and the tension in each rope is 400 N. What is the weight of the person in the middle? ANSWER: What is the force in the rope on the left? ANSWER: What is the force in the rope on the right? ANSWER: What is the total force in the upward direction? ANSWER: Since the total force upward should balance the total weight (downward), what should the total weight (downward) equal to? ANSWER: What is the weight of the scaffold? ANSWER:
