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
Strength of Materials Coefficient of friction is the the friction force acting when the body is in motion the friction force acting when the body is just about to move angle between normal reaction and the resultant of normal reaction and the limiting friction ratio of limiting friction and normal reaction the friction force acting when the body is in motion the friction force acting when the body is just about to move angle between normal reaction and the resultant of normal reaction and the limiting friction ratio of limiting friction and normal reaction ANSWER DOWNLOAD EXAMIANS APP
