increase the effort arm to 8 feet
a lever
Ideal Mechanical Advantage
4
The mechanical advantage is when the fulcrum is closer to the effort and creates a advantage
load arm, effort arm, load, effort, fulcrum!
THE PRODUCT OF EFFORT AND EFFORT ARM IS CALLED MOMENT OF EFFORT.
Effort Arm
4Explanationfor a lever,effort * effort arm = load *load armso by re arranging above equation,load/effort = effort arm/load armNow, as load/effort is called mechanical advantage so,mechanical advantage = effort arm/load armAs total length of rod is 2 m out of which 1.6 m is effort arm so remaining 0.4 m would be load arm. thus on putting values in the above equation, we getmechanical advantage = 1.6/0.4 = 4
effort arm
increase the effort arm to 8 feet
a lever
a lever with an effort arm of 2 inches
increase the effort arm to 8 feet
The portion between the fulcrum and the effort applied in a lever is called effort arm.
Mechanical advantage= effort arm length/ load arm length For Example Effort arm=120 cm Load arm length= 40 cm MA-120/40 = 3
