To solve the problem of determining the minimum speed a motorcyclist must have to prevent slipping while driving on the vertical surface of a cylindrical well, we can follow these steps: ### Step 1: Identify the Forces Acting on the Motorcyclist When the motorcyclist is riding on the vertical wall of the well, two main forces act on him: - The gravitational force (\( F_g = mg \)), acting downward. - The normal force (\( F_n \)), acting perpendicular to the wall of the well. ### Step 2: Understand the Role of Friction ...

In a rotor, a hollow vertical cylindrical structure rotates about its axis and a person rests against the inner wall. At a particular speed of the rotor, the floor below the person is removed and the person hangs resting against the wall without any floor. If the radius of the rotor is 2m and the coefficient of static friction between the wall and the person is 0.2, find the minimum speed at which the floor may be removed Take g=10 m/s^2 .
