Can you lift someone heavier than yourself with a lever?why?

Question

my answer is yes..am i correct??

Answer 1

yes you are right

you would just lift them less distance
load * Load distance = effort * effort distance

distance is from centre
this would balance

if you made effort distance greater then the load would rise.

Answer 2

Yes, have you seen a swing in a park where two children play. If both children are equal in weight, the swing really swings otherwise it goes down the heavier child's side. In the case of a heavier and lighter persons and the lever the moment is to be considered. Distance from the pivot multiplied by the mass gives the moment. So a smaller mass can lift a heavier mass by using a longer lever.

Answer 3

Everyone knows that it is easier to close
a door by pushing it from the outer edge
rather than from the hinge side.

In this way, for the same force applied
" the rotation effort " (or torque) is
proportional to the distance between
the effort application point and the fixed
point or "fulcrum".

The product of this distance combined
with the degree of effort applied is
known as the moment.
