well it turns out that

pressure is just how much force is applied in area

like if you’re standing on your feet vs tip toeing

you can feel your toes being squished by floor much more

when you lift your heels off the ground

it’s actually not a change in force which is your weight, but higher pressure

applied by floor’s reactive force back to your toes

if we can apply small force in large area like a brake pedal

hydraulic pressure is same throughout the fluid in the closed system (connected by hose)

so reactive force can be great in small area like brakepads

or it can be like a gear/seesaw leverage where torque is same

but you use large gear to turn more distance easily

and smaller gear turns small distance but with higher force
