Order the diagrams to show the relationship between the length of the effort arm and the force needed to lift the weight.RESET

To order the diagrams showing the relationship between the length of the effort arm and the force needed to lift the weight, we can follow these steps:

1. Break Down the Problem

• Determine the concept of the effort arm and its influence on the required force to lift a given weight.
• Identify the diagrams that depict various lengths of the effort arm.

2. Relevant Concepts

• The principle of levers states that the force needed to lift a weight is inversely proportional to the distance (length) of the effort arm from the fulcrum: $F_1 \cdot d_1 = F_2 \cdot d_2$ Where:
  • $F_1$ = force applied
  • $d_1$ = length of the effort arm
  • $F_2$ = weight to be lifted
  • $d_2$ = distance from the fulcrum to the weight

3. Analysis and Detail

• If the effort arm increases, the force needed to lift the weight decreases. Hence, diagrams should be ordered from the shortest to the longest effort arm, which corresponds to the force needed.

4. Verify and Summarize

• Check that each diagram accurately reflects the relationship between the effort arm length and the necessary lifting force.

Final Answer

Order the diagrams from shortest effort arm to longest effort arm, which corresponds to the force needed to lift the weight decreasing as the effort arm length increases.
