Classify the following machine and draw the figure net cracker, wheel barrow,scissors, fire tongs.

Answer 1

Answer:

Answer

A class I lever has the fulcrum between effort and load. In an ice tong and tweezer, effort is between fulcrum and load. Hence, they are class III lever. In scissors and pliers, fulcrum is between effort and load. Therefore they are class I levers .

A class II lever has the load between effort and fulcrum. In wheel barrow, paper cutter and nut cracker, load is between effort and fulcrum. Therefore, they are class II levers .

A class III lever has the effort between fulcrum and load. A broom and fishing rod have the effort between fulcrum and load. Therefore, they are class III levers.

Hence, in the given table, I and III are the correct examples of I, II and III class levers .
