Strength of Materials The magnitude of two forces, which when acting at right angle produce resultant force of VlOkg and when acting at 60° produce resultant of Vl3 kg. These forces are 3 and 1 kg 2 and V6 2 and 5 V5 and V5 3 and 1 kg 2 and V6 2 and 5 V5 and V5 ANSWER DOWNLOAD EXAMIANS APP
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 vertically horizontally along the plane at an angle equal to the angle of friction to the inclined plane vertically horizontally along the plane at an angle equal to the angle of friction to the inclined plane ANSWER DOWNLOAD EXAMIANS APP
