Final answer:
Tools greater than 30 - 32 pounds should have a counterweight or suspension system. A simple fulcrum can be used to weigh objects exceeding the maximum reading on a spring scale. The ladder is more likely to slip when the painter is near the top.
Step-by-step explanation:
Tools greater than 30 - 32 pounds should have a counterweight or suspension system.
When weighing an object whose weight exceeds the maximum reading on a spring scale, a simple fulcrum can be used. By placing the object on one end of the fulcrum and the spring scale on the other end, the scale will measure the force exerted by the object on the fulcrum. This force can then be equated to the weight of the object.
Answer: The ladder is more likely to slip when the painter is near the top. This is because the weight of the painter creates a greater downward force on the ladder, increasing the likelihood of slippage.
