Imagine that you need to lift a heavy object using a lever, where one side is longer than the other. The lever has two different types: an interfixed lever and an inter-resistant lever. In each case, follow the steps to answer the questions: a) Identify which type of lever is most suitable for lifting the object with the least possible effort and why. Relate the types of levers to their fulcrum position, effort, and resistance. b) Using the lever rule or the jargon law, calculate the force required to lift the 200kg object, if the long side of the lever measures 4m and the short side measures 1m. c) Discuss the possible risks involved in the use of levers in everyday life and suggest safety behaviors to minimize these risks.
