Design No	Objective	Score allotted	Justification for the score
01	Safety	-18	While operating with foot people might hurt their leg
	Ease of Use	-16	It is not easy to apply horizontal force with leg
	Portability	00	It is importable
	Use of Standard Parts	04	Strong and quality parts are used for making the machine
	Cost	06	It costs less than pulley system
02	Safety	18	It is very safe to operate vertically downwards
	Ease of Use	16	It is easy to apply force downwards as our body weight also acts in input force
	Portability	-03	It is importable
	Use of Standard Parts	04	Strong and quality parts were used for making the machine
	Cost	06	It costs less than pulley system
