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
Strength of Materials The algebraic sum of the resolved parts of a number of forces in a given direction is equal to the resolved part of their resultant in the same direction. This is as per the principle of balance of force forces independence of forces resolution of forces. balance of force forces independence of forces resolution of forces. ANSWER DOWNLOAD EXAMIANS APP
