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