9. Define the term "coefficient of limiting friction" between two surfaces. A body of mass10Kg is placed on an inclined surface of angle 30° If the coefficient of limiting friction is1/V3. Find the force required to just push the body up the inclined surface. The force isbeing applied parallel to inclined surface

Answer»

the force required is 100 N

pls explain

the force required wil be the sum of the force due to weight of block down the incline and the frictional force due to static friction on the surface. hence the force along the incline due to wieght of block is 100 cos (60) = 50 N. also the friction force = 10 sin(60)*1/root(3) = 50 N
