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