The normal force exerted by a surface is a reaction force that opposes the force pressing the cup against it. The material of the cup does not affect this force because it is a result of the interaction between the cup and the surface it is resting on, not a property of the cup itself. As long as the cup is in contact with the surface, the normal force remains the same regardless of the cup material.
What else can I help you with?
Why doesn't normal force Fn depend on the cup material used?
The normal force depends on the weight of the object pressing down on the cup, not the material of the cup itself. The material might affect how the cup distributes the normal force, but it doesn't directly influence the magnitude of the normal force.
Does the frictional force depend on the area of surface contact?
No, the frictional force does not depend on the area of surface contact. It is primarily determined by the nature of the surfaces in contact and the normal force pressing the surfaces together. The coefficient of friction between the surfaces also plays a role in determining the magnitude of the frictional force.
How does the coefficient of friction depend upon the normal force between the surfaces in contact?
-- The friction force changes, and is directly proportional to the normal force. -- The coefficient of friction doesn't change. It is the proportionality constant in the first statement.
What does the strength of the force of friction depend?
The strength of the force of friction depends on the nature of the surfaces in contact and the normal force pressing them together. Rougher surfaces and higher normal forces typically result in stronger friction forces.
What is the relationship between normal stress and shear stress in a material under mechanical loading?
Normal stress and shear stress are two types of stresses that act on a material under mechanical loading. Normal stress is a force applied perpendicular to the surface of the material, while shear stress is a force applied parallel to the surface. The relationship between normal stress and shear stress depends on the material's properties and the direction of the applied forces. In general, normal stress and shear stress can interact and affect each other, leading to complex mechanical behaviors in the material.

Does the frictional force depend on the area of surface contact?
No, the frictional force does not depend on the area of surface contact. It is primarily determined by the nature of the surfaces in contact and the normal force pressing the surfaces together. The coefficient of friction between the surfaces also plays a role in determining the magnitude of the frictional force.
Why do each substance have different amount of resistance?
Resistance of a material is depend on the force required to withdraw electrons from the atoms of that material.
How does the coefficient of friction depend upon the normal force between the surfaces in contact?
-- The friction force changes, and is directly proportional to the normal force. -- The coefficient of friction doesn't change. It is the proportionality constant in the first statement.
What does the strength of the force of friction depend?
The strength of the force of friction depends on the nature of the surfaces in contact and the normal force pressing them together. Rougher surfaces and higher normal forces typically result in stronger friction forces.
Is 1 meter cube concrete wt depend upen material?
Yes. And the local force of gravity.
If friction isn't dependent on surface area but only on the coefficient of friction between two surfaces and the reaction force then why do racing cars use bigger tires with greater area?
Friction doesnt not depend on the surface area...but the force of friction does! We cannot change the friction of a material but we can change the force due to that friction on another material in contact with it. Using this concept, racing cars have bigger tires to minimise the force of friction acting on them. They cannot change the friction of the road, so they change the resultant force on the tires.
What is the relationship between normal stress and shear stress in a material under mechanical loading?

What two things does the force of friction depend upon?
The force of friction depends on the nature of the surfaces in contact and the normal force pressing the surfaces together. A rough surface will create more friction compared to a smooth surface, and increasing the normal force pressing the surfaces together will increase the friction force.
Is the coefficient of friction independent of the narmal force?
No, the coefficient of friction is not independent of the normal force. In fact, the coefficient of friction is defined as the ratio of the frictional force to the normal force between two surfaces in contact. It is a material property that quantifies the resistance to sliding between the surfaces.
What does the friction force vs normal force graph reveal about the relationship between friction force and normal force?
The friction force vs normal force graph shows that there is a direct relationship between the friction force and the normal force. As the normal force increases, the friction force also increases. This indicates that the friction force is proportional to the normal force.
Does the frictional force depends on the contact area?
The contact area hardly affects the frictional force. The frictional force depends on the normal force, and the coefficient of friction, which is a property you have to look up (or measure) for every pair of materials.
