A log of mass 40 kg and length 2 m rests as shown. The log makes an angle of =53 degrees with the floor. The centre of gravity of the log is at its midpoint. The vertical wall is very smooth and offers neglibigle frictional forces. What is the magnitude of the vertical force exerted by the floor on the log at the point of contact? N What is the magnitude of the horizontal (normal) force exerted by the wall on the log? N What is the magnitude of the horizontal frictional force exerted by the floor on the log? N For the log to remain stable, the floor must be rough enough to provide the required frictional force. What is the minimum value of the coefficient of static friction between the floor and the log that will provide stability
