A fishing rod is classified as _____ lever.
A) Class I
B) Class II
C) Class III
D) Can’t say.
Solution
For fishing rod, input force (effort) has to be close to the fulcrum. The fulcrum has to be on one end of the lever and the load has to be at the other end of the lever. Effort is between fulcrum and load.
Complete step by step answer:
A lever is one of the six types of simple machines. Those simple machines include wedges, wheel and axles, inclined planes, screws, pulleys. Levers have three parts. They are effort, fulcrum and a load.There are three types (classes) of levers. Class I levers have fulcrum in between effort and load. Class II levers have the load in between effort and fulcrum. Class III levers have effort between load and fulcrum.
Usually a fishing rod is fixed at the base which is the fulcrum and it is held between the fixed end and the other end of the rod, load is present at the end. This implies that effort is applied between the fulcrum and the load. A third class lever is a lever where the effort is applied between the fulcrum and the load. Hence the fishing rod is class III lever.
Thus the right answer is Option C, Class III.
Note: The class of any lever can be easily identified by observing the nature of the lever. Just find where we need to put the effort and fulcrum is a point where the level is supported.
