Design a disc brake with a double caliper. Each side of the disc has two 40-mm-diameter pads. The center of the brake pads is at a radius of 150 mm. The outside diameter of the disk is 360 mm. The pads have woven linings that provide a coefficient of friction of approximately 0.25. The average pressure on the pads is to be limited to 400 kPa.

What is the maximum clamping force (F)?

How much is the braking torque for the above clamping force F?

The above braking system is used to bring a rotating assembly with a mass moment of inertia of 8 N m s² to a stop from a rotating speed of 900 rpm.

If an instantaneous full application of the brake is assumed, how long does this take for the machine to come to a complete stop?
