You push a heavy crate harder and harder but it stays put. Static friction rises to match your push up to its:
AModelled limit
BMaximum limit
CMinimum limit
DMeasured limit
Answer & Solution
Correct answer: B. Maximum limit
1. Static friction is a responsive force, not a fixed one.
2. It grows equal and opposite to whatever you apply.
3. It does so only up to its maximum limit.
