Its 1st order example plz correct it
its not second type of lever
smith tong is first type of lever
1st order
Its First order
Correct answer: option B (first order)
First Order Levers: First class levers have the fulcrum between the force and the load. In using a screwdriver to lift the lid from a paint tin you are moving the effort over a greater distance than the load.
Second Order Levers: In second class levers the load is between the effort (force) and the fulcrum. A common example is a wheelbarrow where the effort moves a large distance to lift a heavy load, with the axle and wheel as the fulcrum.
Third-order levers: With third class levers the effort is between the load and the fulcrum, for example in barbecue tongs.
