Question

Answer 1

a option is true.......

Answer 2

‘Second and third class levers’ both have d) the fulcrum at ‘one end of the lever and explanation’.

In both ‘first class lever’ and ‘second class lever’, the effort is applied only at ‘one end of the lever’ whereas the load is applied to the other end of the lever. The see-saws and scissors represent the first class levers whereas a wheelbarrow represents the second class lever.

The first class leverage occurs when the ‘head is lifted off the chest’, but the second class leverages are not common in the body.
