Calculate Sliding Friction on Plate at 60 Degrees, 14 Pitch Dia.

In summary: Additionally, the type of material and surface finish of both the plate and bearing surface will also affect the amount of heat generated. In summary, the sliding friction and heat generated in this situation can be calculated using the equation Friction = µ × F × A and will vary depending on factors such as material type, surface finish, load, and speed.

I am working on a new design on pumps. Would some one help me to calculate the sliding friction if the following are known.

a plate is at an angle at 60 degrees to its horizontal axis.
a flat bearing surface is sliding at 14 pitch dia on the plate. (consider a ball cut into half, Use the half as a bearing, bottom ( flat) of the half is sliding on the plate at the above pitch dia.)
force on the bearing pushing the flat against the plate is 20,000 lbs.
Consider the area of the bearing (flat surface) 4" in dia.
the plate is spinning at 200 rpm at an angle of 60 degrees to a horizontal axis shaft.

what would be the friction generated and heat generated due to friction, if you consider a gound surface between the two contact surfaces.

The sliding friction generated in this situation depends on many factors, including the type of material and surface finish of both the plate and the bearing surface, the coefficient of static friction between the two materials, the load applied to the bearing surface, and the speed of the plate. In general, the friction generated in this situation can be calculated with the following equation: Friction = µ × F × A Where µ is the coefficient of static friction between the plate and bearing surface, F is the force acting on the bearing surface (20,000 lbs in this case), and A is the area of the bearing surface (4" in diameter).The heat generated due to friction will depend on the amount of friction generated, as well as the speed of the plate. Generally, the higher the speed and the greater the friction, the more heat will be generated.
 

1. What is sliding friction?

Sliding friction is the force that resists the motion of an object across a surface. It occurs when two surfaces are in contact and one surface slides or moves relative to the other.

2. How is sliding friction calculated?

Sliding friction is calculated by multiplying the coefficient of friction between the two surfaces by the normal force acting on the object. The normal force is equal to the weight of the object.

3. What is the coefficient of friction?

The coefficient of friction is a measure of how rough or smooth two surfaces are in contact. It is a dimensionless value, typically represented by the symbol µ (mu). A higher coefficient of friction indicates a rougher surface, and a lower coefficient of friction indicates a smoother surface.

4. What is the angle of inclination in sliding friction?

The angle of inclination is the angle between the surface and the direction of motion of the object. In the case of calculating sliding friction on a plate at 60 degrees, the angle of inclination would be 60 degrees.

5. How does the pitch diameter affect sliding friction?

The pitch diameter is the diameter of the circle formed by the points where the two surfaces are in contact. It affects sliding friction by changing the surface area of contact between the two surfaces. A larger pitch diameter will result in a larger surface area and potentially higher sliding friction.
