The correct relationship between the effort (E), load (L), and mechanical Advantage (M.A) is
M.A=L×E
M.A×E=L
M.A×L=E
None of these
Explanation
Hence the correct answer is M.A×E=L
The lever for which the mechanical advantage is less than 1 has the :
(a) fulcrum at the midpoint between the load and effort.
(b) load between the effort and fulcrum.
(c) the effort between the fulcrum and load.
(d) load and effort acting at the same point.
Assertion (A): Mechanical advantage (MA) of a simple machine is always greater than one.
Reason (R): MA=LoadEffort
In a machine, a load of 490 N is supported by an effort of 7N. If the distance of fulcrum from the point where the load acts is 10m, find the mechanical Advantage and length of the effort arm.
Given the load=420N, Effort applied=350N. Find mechanical advantage (MA), also find the type of lever.
Given the load=10N, Effort applied=10N. Find mechanical advantage (MA), also find the type of lever.
