Strength of Materials Least force required to draw a body up the inclined plane is W sin (plane inclination + friction angle) applied in the direction along the plane vertically at an angle equal to the angle of friction to the inclined plane horizontally along the plane vertically at an angle equal to the angle of friction to the inclined plane horizontally ANSWER DOWNLOAD EXAMIANS APP
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 velocity of sliding independent of the area of contact surfaces proportional to normal load between the surfaces dependent on the materials of contact surface proportional to velocity of sliding independent of the area of contact surfaces proportional to normal load between the surfaces ANSWER DOWNLOAD EXAMIANS APP
