Chapter Summary for MCQ: Simple Machines

Simple Machines

πŸ”Ή 1. What is a Simple Machine?

  • A simple machine is a device that makes our work easier by changing the direction or magnitude of force.

  • It does not multiply energy, only redistributes or redirects it.

πŸ”Ή 2. Types of Simple Machines

There are six basic types:

  1. Lever – e.g., seesaw, scissors

  2. Inclined Plane – e.g., ramp

  3. Pulley – e.g., flagpole, well

  4. Wheel and Axle – e.g., steering wheel

  5. Wedge – e.g., knife, axe

  6. Screw – e.g., jar lid, drill

πŸ”Ή 3. Lever and Its Classes

  • A lever is a rigid bar that pivots around a fixed point (fulcrum).

  • Three classes:

    • Class I: Fulcrum in the middle (e.g., scissors)

    • Class II: Load in the middle (e.g., wheelbarrow)

    • Class III: Effort in the middle (e.g., tongs)

πŸ”Ή 4. Key Terms

  • Load (L): The object to be moved.

  • Effort (E): Force applied to move the load.

  • Fulcrum (F): Pivot point of a lever.

πŸ”Ή 5. Mechanical Advantage (MA)

  • Ratio of load to effort:

    MA=LoadEfforttext{MA} = frac{text{Load}}{text{Effort}}

  • MA > 1: Less effort needed

  • MA = 1: Just changes direction

  • MA < 1: More effort needed (e.g., speed gain)

πŸ”Ή 6. Velocity Ratio (VR)

  • Ratio of distance moved by effort to distance moved by load:

    VR=DistanceΒ byΒ EffortDistanceΒ byΒ Loadtext{VR} = frac{text{Distance by Effort}}{text{Distance by Load}}

πŸ”Ή 7. Efficiency (%)

  • How effectively a machine works:

    Efficiency=(MAVR)Γ—100text{Efficiency} = left( frac{text{MA}}{text{VR}} right) times 100

  • Efficiency is always less than 100% due to friction and energy loss.

πŸ”Ή 8. Pulley System

  • A fixed pulley changes the direction of force (VR = 1).

  • A movable pulley reduces effort (MA > 1).

  • In a combination pulley, VR and MA depend on the number of ropes supporting the load.

πŸ”Ή 9. Inclined Plane

  • An inclined surface used to raise heavy objects.

text{MA} = frac{text{Length of slope}}{text{Height of slope}}
]

🧠 MCQ Focus Points

  • Know all machine types with examples.

  • Be clear on MA, VR, and efficiency formulas.

  • Identify lever classes by positions of load, effort, and fulcrum.

  • Understand direction change vs. force gain in pulleys and levers.

  • Recognise real-life applications of each type.
