This formula uses 5 Variables

Variables Used

Force of Friction - (Measured in Newton) - Force of Friction used in merchant circle where the friction force is equal to the product of coefficient of friction and normal force.
Real Area of Contact - (Measured in Square Meter) - Real Area of Contact is defined as the actual or real area that is in actual contact with the other part.
Proportion of Area of Metallic Contact - Proportion of Area of Metallic Contact is defined as the proportion of the area supporting the load in which metal came in contact.
Shear Strength of Softer Metal - (Measured in Pascal) - Shear Strength of Softer Metal refers to the maximum stress that the metal can withstand when subjected to a shear force before it starts to deform or fail.
Shear Strength of Softer Lubricant Layer - (Measured in Pascal) - Shear Strength of Softer Lubricant Layer refers to the maximum stress that the lubricant material can withstand before it undergoes shear deformation.

STEP 1: Convert Input(s) to Base Unit

Real Area of Contact: 1250 Square Millimeter --> 0.00125 Square Meter (Check conversion here)
Proportion of Area of Metallic Contact: 0.5 --> No Conversion Required
Shear Strength of Softer Metal: 0.03 Newton per Square Millimeter --> 30000 Pascal (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

F_f = A_c*((γ_m*τ₁)+((1-γ_m)*τ₂)) --> 0.00125*((0.5*30000)+((1-0.5)*10000))

Evaluating ... ...

F_f = 25

STEP 3: Convert Result to Output's Unit

25 Newton --> No Conversion Required

FINAL ANSWER

25 Newton <-- Force of Friction

what is friction force and its types?

The friction force is the force exerted by a surface as an object moves across it or makes an effort to move across it. There are at least two types of friction force - sliding and static friction. Though it is not always the case, the friction force often opposes the motion of an object.
