N = p*l*w
This formula uses 4 Variables
Variables Used
Normal Reaction on Brake - (Measured in Newton) - Normal Reaction on Brake is the force exerted by the drum or the disc onto the brake or vice versa.
Pressure Between Block and Brake Drum - (Measured in Pascal) - Pressure Between Block and Brake Drum is the permissible amount of pressure between the block and the brake drum.
Length of Block of Brake - (Measured in Meter) - Length of Block of Brake is defined as the length of the block of the brake with a short shoe.
Width of Brake Block Shoe - (Measured in Meter) - Width of Brake Block Shoe is defined as the width of the block of a brake with the short shoe.
STEP 1: Convert Input(s) to Base Unit
Pressure Between Block and Brake Drum: 2.1 Megapascal --> 2100000 Pascal (Check conversion here)
Length of Block of Brake: 110 Millimeter --> 0.11 Meter (Check conversion here)
Width of Brake Block Shoe: 25 Millimeter --> 0.025 Meter (Check conversion here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
N = p*l*w --> 2100000*0.11*0.025
Evaluating ... ...
N = 5775
STEP 3: Convert Result to Output's Unit
5775 Newton --> No Conversion Required
FINAL ANSWER
5775 Newton <-- Normal Reaction on Brake

Normal Reaction Force Formula

Normal Reaction on Brake = Pressure Between Block and Brake Drum*Length of Block of Brake*Width of Brake Block Shoe
N = p*l*w

Define Normal Reaction?

The force exerted by a surface on an object in contact with it which prevents the object from passing through the surface; the force is perpendicular to the surface, and is the only force that the surface exerts on the object in the absence of frictional forces.
