derivation of pedal equation

If you look at the emergency pedal assembly you should see a lever that has a "u" curve at the bottom of the lever (it is up in the body part of the assembly) pull or pry the lever rearward it should release the pedal (THE PEDAL WILL RELEASE HARD SO...BE CAREFUL)

Basically, it IS a curve.

c curve & d curve mcb difference

simple curve is a curve which doesnot cross itself,it neednot be closed.......

but a simple closed curve is a curve which is simple and also closed.

every simple closed curve is a simple curve but not vice versa.
