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

Strength of Materials A semi-circular disc rests on a horizontal surface with its top flat surface horizontal and circular portion touching down. The coefficient of friction between semi-cricular disc and horizontal surface is i. This disc is to be pulled by a horizontal force applied at one edge and it always remains horizontal. When the disc is about to start moving, its top horizontal force will unpredictable remain horizontal slant down towards direction of pull slant up towards direction of pull unpredictable remain horizontal slant down towards direction of pull slant up towards direction of pull ANSWER DOWNLOAD EXAMIANS APP
