Which one of the following is a Class III lever? (E-effort, F-fulcrum and L-load)
Which one of the following is a Class III lever? (E-effort, F-fulcrum and L-load)
E - Effort, F - Fulcrum, L - Load
E - Effort, F - Fulcrum, L - Load
E - Effort, F - Fulcrum, L - Load
E - Effort, F - Fulcrum, L - Load
The correct option is D
E - Effort, F - Fulcrum, L - Load
Depending upon the relative positions of the effort, load and fulcrum, levers are classified into 3 types.
(1) Class I levers - Fulcrum is in between load and effort.
(2) Class II levers - Load is in between fulcrum and effort.
(3) Class III levers - Effort is in between fulcrum and load.
E - Effort, F - Fulcrum, L - Load
Depending upon the relative positions of the effort, load and fulcrum, levers are classified into 3 types.
(1) Class I levers - Fulcrum is in between load and effort.
(2) Class II levers - Load is in between fulcrum and effort.
(3) Class III levers - Effort is in between fulcrum and load.
