Question

It is easier to draw up wooden block along an inclined plane than have it up vertically, principally because

• A. The friction is reduced
• B. The mass becomes smaller
• C. Only a part of weight has to be overcome
• D. All of these

Answer 1

The correct option is C Only a part of weight has to be overcome

On an inclined plane, the component of the weight, $mg\cos \theta$ gets balanced by reaction. The component $mg\sin \theta$ acting parallel to plane is only to be overcome.
