What is the difference between roughness and flatness?
The difference between roughness and flatness is that one, flatness, is the shape of an object. Roughness is the surface or texture of an object.
Instrument used to measure roughness of road?
One instrument used to measure roughness of roads is the response type road roughness meters (RTRRMs)
What force is created by the surface of one object rubbing against another object?
The force created by the surface of one object rubbing against another object is called friction. Friction opposes the relative motion between two surfaces in contact and is influenced by factors such as the roughness of the surfaces and the force pressing the surfaces together.
Is this statement true or false Real texture is experienced by touching and feeling a surface?
True. Real texture refers to the physical surface quality of an object that can be experienced by touching and feeling it with one's hands or body. This tactile experience allows individuals to perceive the roughness, smoothness, hardness, or softness of a surface.
On a flat surface the coefficient of friction is a ratio between and the weight of the object?
The coefficient of friction on a flat surface is a measure of the force required to move one object over another. It is the ratio between the force of friction and the normal force acting on the object, which is determined by the weight of the object pressing on the surface.
How can one measure the coefficient of friction accurately?
To measure the coefficient of friction accurately, one can use a device called a friction tester or a force sensor. The device applies a known force to an object and measures the force required to move the object across a surface. By dividing the force needed to move the object by the force applied, one can calculate the coefficient of friction. This method provides a precise measurement of the friction between the object and the surface.
How can one determine the surface charge density of an object?
To determine the surface charge density of an object, you can divide the total charge on the object by its surface area. This will give you the amount of charge per unit area on the object's surface.
What object has at least one curved surface and one flat surface?
half circle
How can one accurately measure the chamfer angle of a given object?
To accurately measure the chamfer angle of an object, you can use a protractor or a chamfer gauge. Place the protractor or chamfer gauge against the chamfered edge of the object and align it with the surface to determine the angle. Alternatively, you can use a digital angle finder for more precise measurements.
How can I measure the size of an object from an image?
One way to measure the size of an object from an image is to use a known reference object of a standard size in the same image. By comparing the size of the reference object to the size of the object you want to measure, you can calculate the size of the object in the image.
Is it true that the thing that affects how fast it falls is the objects surface area?
Surface area is ONE thing that can affect how fast an object falls. Two forces determine how fast an object falls - the force of gravity and the opposing drag on the object from the medium it is falling through. In the case of an object falling in a vacuum, there is no drag so the object falls strictly according to the law of gravity. If an object is dropped through a fluid such as air or water, it can reach a terminal velocity where the force of gravity is exactly counterbalanced by the opposing drag on the object. In this case acceleration ceases - although motion does not. In other words, the object continues to fall, but it doesn't speed up. Drag force is a function of object velocity, viscosity of the fluid it is falling through, the surface area of the falling object, the surface roughness of the falling object, and the geometry of the falling object (spheres usually have less drag than cubes for example).
What are all factors affecting frictional force?
Factors affecting frictional force include the roughness of the surfaces in contact, the force pressing the surfaces together, the nature of the materials involved, and any lubricants present. These factors determine the amount of resistance encountered when attempting to slide one surface over the other.
