To solve the problem of determining the minimum coefficient of friction between a thin rod and a floor at which a person can slowly lift the rod from the floor to the vertical position, we can follow these steps: ### Step-by-Step Solution: 1. **Understanding the Setup**: - We have a thin rod lying on the floor. A force \( F \) is applied at the end of the rod, perpendicular to its length, to lift it vertically. - The rod has a mass \( m \) and experiences gravitational force \( mg \) acting downwards. ...
