Solution Steps

Step 1: Identify the Type of Lever

Scissors are a common tool used for cutting, and they function as a type of lever. To determine which class of lever they belong to, we need to analyze the positions of the fulcrum, effort, and load.

Step 2: Analyze the Lever Components
  • Fulcrum: The pivot point of the scissors, which is located at the screw or pin that holds the two blades together.
  • Effort: The force applied by the user at the handles of the scissors.
  • Load: The resistance or the material being cut, which is located between the blades.
Step 3: Determine the Lever Class

In a first-class lever, the fulcrum is located between the effort and the load. This matches the configuration of scissors, where the fulcrum (the screw) is between the handles (effort) and the blades (load).

Read the excerpt from chapter 10 of Animal Farm. "Four legs good, two legs BETTER! Four legs good, two legs BETTER! Four legs good, two legs BETTER!" It went on for five minutes without stopping. And by the time the sheep had quieted down, the chance to utter any protest had passed, for the pigs had marched back into the farmhouse. How does Orwell use irony to develop the theme that the abuse of language is part of the abuse of power? Orwell uses irony to emphasize the sheep's insistence that they have changed their views on animalism. Orwell uses irony to show how the sheep are chanting in a way that disturbs the other animals. Orwell uses irony to highlight how the sheep are repeating words that go against their self-interest. Orwell uses irony to draw attention to the fact that the sheep are smart enough to communicate verbally.
