How do you improve torque and power transmitted without slipping using the uniform pressure theory and uniform wear theory?

the torque transmitting capacity according to uniform pressure theory is more than the uniform wear theory. but if you want to improve the torque transmitting capacity you have to increase the following parameters 1)coefficient of friction 2)number of friction and pressure plates 3)dimensions of the plates

Why is friction needed in the brakes?

Newton's First Law of Motion states: "An object in motion, remains in motion, unless acted upon by an outside force". Friction is an additional outside force that stops the motion of a vehicle faster. Without friction, the vehicle would never stop until it crashed into something.

the ice disappears/melts due to its friction with the air outside causing it to melt.

Why does a ball that is rolling come to a stop?

a round object rotates when there is a force acting tangentially.. in this case friction force is acting tangentially... so it should be rolling without stopping.. but it does stop since the weight is not balanced by its normal force(i.e. normal force and weight are not acting on the same point.)
