Variables Used
Coefficient of Friction for Brake - Coefficient of Friction for Brake is the ratio defining the force that resists the motion of the brake pad in relation to the brake disc or drum in contact with it.
Torque absorbed by brake - (Measured in Newton Meter) - Torque absorbed by brake is described as the turning effect of force on the axis of rotation of the brake disc.
Actuating force on brake - (Measured in Newton) - Actuating force on brake is defined as the amount of force required to actuate the braking mechanism.
Friction Radius of Brake - (Measured in Meter) - Friction Radius of Brake specifies a characteristic radius for a disc clutch/brake.
STEP 1: Convert Input(s) to Base Unit
Torque absorbed by brake: 485000 Newton Millimeter --> 485 Newton Meter (Check conversion here)
Actuating force on brake: 11000 Newton --> 11000 Newton No Conversion Required

Define Disk Brake?

A disc brake is a type of brake that uses the calipers to squeeze pairs of pads against a disc or a "rotor" to create friction. This action slows the rotation of a shaft, such as a vehicle axle, either to reduce its rotational speed or to hold it stationary.
