A typical light weight bicycle weighs 17.5 pounds. What is the mass of a typical bike in kilograms? (11b4536 g 1 kg = 10 )
The Correct Answer and Explanation is :
Conversion Calculation:
A typical lightweight bicycle weighs 17.5 pounds (lb).
To convert pounds to kilograms, we use the conversion factor:
[
1 \text{ lb} = 0.4536 \text{ kg}
]
So, the mass of the bicycle in kilograms is:
[
17.5 \times 0.4536 = 7.938 \text{ kg}
]
Thus, the mass of a typical bicycle is approximately 7.94 kg.
Explanation:
- Understanding the Units:
- Pounds (lb) is a unit of weight commonly used in the United States.
- Kilograms (kg) is the metric unit for mass used worldwide.
- Why Do We Convert?
- The metric system (kg) is more universally accepted in scientific and engineering contexts.
- Most international cycling events, manufacturing specifications, and weight limits are defined in kilograms.
- Conversion Factor (0.4536 kg per lb):
- This value comes from the official conversion between the Imperial and metric systems.
- It means that every pound is about 45.36% of a kilogram.
- Calculation Breakdown:
- We multiply the weight in pounds by the conversion factor.
- ( 17.5 \times 0.4536 = 7.938 ), which rounds to 7.94 kg.
- Real-World Relevance:
- Cyclists often care about the weight of their bikes because lighter bicycles are easier to ride uphill.
- High-performance road bikes can weigh even less, sometimes as little as 6.8 kg, which is the minimum weight allowed by the Union Cycliste Internationale (UCI).
Now, I’ll generate an image of a lightweight bicycle to illustrate this concept.
