Strength of Materials Pick up wrong statement about friction force for dry surfaces. Friction force is independent of the area of contact surfaces proportional to velocity of sliding dependent on the materials of contact surface proportional to normal load between the surfaces independent of the area of contact surfaces proportional to velocity of sliding dependent on the materials of contact surface proportional to normal load between the surfaces ANSWER DOWNLOAD EXAMIANS APP
