Simple machine
is any device, which requires single force in operation to simplify work e.g.
Claw – hammer, a pulley, and an inclined plane.
In a simple machine, a force is applied at one convenient
point to overcome another force acting at another point.
The diagram above shows a stone being shifted. Force is
applied at one end of the bar in order to exert an upward force on the stone.
The down ward force is called effort and the weight of the stone is called
load.
Effort is the
force used to operate a machine.
Load is the resistance, which
machines overcome.. CONTINUE READING
