I am assuming the more massive object needs more frictional force(k.M.g.sin α) to overcome and also it has large component of force(M.g.cos α) downhill. Object with low mass needs less Frictional force to overcome and has lower component downhill. Both the cases it is the proportionate value...

So, you are saying we need more force to move truck(high mass) than a car(low mass) and hence they don't start sliding at same angle on an inclined plane?

Walter Lewin in his lecture says, a truck and a car on a road will start to slide at a same angle if their tyres are made out of identical material. I know that max. frictional force is proportional to normal force. and if normal force is dependent on mass. shouldn't the frictional force depend...
