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