A body weighing 100 lb rests on an inclined plane, as shown. The coefficient of static friction between the body and the plane is 0.40. Compute the force P that will cause impending motion

  • (a) up the inclined plane.

  • (b) down the inclined plane.

Draw Free-body diagram 

Solve most simple way

The diagram illustrates a block on an inclined plane. The weight of the block, labeled as \( W \), is 100 pounds and is represented by a downward arrow. An external force \( P \) is applied parallel to the incline.

The inclined plane is at an angle, forming a right triangle with base lengths labeled 3 and 4, suggesting a 3-4-5 triangle. The surface of the incline is represented with parallel lines to indicate friction or roughness. 

This setup is commonly used to study the components of forces on an incline, frictional forces, and resolving forces into perpendicular and parallel components relative to the incline.
