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