4. Mechanical Advantage (MA)

Try these first

1. 1.

   What is Mechanical Advantage?

   Hint

   Think about force and how machines make it easier to move things.

2. 2.

   Define Input Force.

   Hint

   Consider the effort you put in to use a machine.

3. 3.

   What does Mechanical Advantage measure?

   • Speed
   • Force
   • Force and Speed

   Hint

   Think about the two aspects of how machines work.

4. 4.

   True or False: A higher Mechanical Advantage always leads to higher speed.

   • True
   • False

   Hint

   Consider the trade-off between speed and power.

5. 5.

   Design a simple lever with three different configurations. Calculate the Mechanical Advantage for each configuration and discuss which configuration is most effective for lifting a 100 kg weight.

   Hint

   Draw diagrams for each configuration and measure lengths to set up your calculations.

6. 6.

   Explain how changing the lengths of links in a four-bar linkage can affect the speed and force output when designed to lift a load of 1500 N.

   Hint

   Visualize how each link's motion affects potential force output during operation.
