Question

Define and example of plowing effect ( friction). ​

Answer 1

Explanation:

The rolling ball test is primarily intended for quality control of adhesive tapes but may also be used to investigate adhesive coatings. The motion of the rolling ball is arrested by (1) the adhesion between the ball and the adhesive, known as “grab” and (2) the “plowing effect” or energy required to push adhesive from the ball’s path.

Answer 2

Answer:

Friction is a force that resists the relative motion between two objects or materials. The causes of the resistive force of friction are:

#Molecular Adhesion

#Surface Roughness

#Plowing effect

Adhesion is a molecular force that arises when two materials are brought close to each other.

Surface roughness is a factor in friction when the materials are rough enough to cause serious abrasion.

When one or more of the materials are relatively soft, much of the resistance to movement is caused by deformations or a plowing effect.

Explanation:

The causes of the resistive force of friction are molecular adhesion, surface roughness, and the plowing effect. ... When one or more of the materials is relatively soft, much of the resistance to movement is caused by deformations or a plowing effect.

For example, when you stand on a rug, you sink in slightly, which causes resistance when you try to drag your feet along the rug's surface. Another example is how rubber tires flatten out at the area on contact with the road. When materials deform, you must "plow" through to move, thus creating a resistive force.
