What is the main reason a bicycle becomes easier to pedal when the chain is well-oiled?
easy Q1 of 15
Step-by-Step Solution
Step 1: Understand friction in mechanical systems
Friction between moving parts causes resistance and makes pedaling harder.Step 2: Effect of oiling the chain
Oiling reduces friction between the chain and gears, making pedaling easier.Final Answer:
Reduced friction between moving parts → Option CQuick Check:
Oiling chain = Reduced friction ✅
Quick Trick: Lubrication reduces friction in machines.
Common Mistakes:
MISTAKES- Confusing friction increase with lubrication effect.
