Did you know?

Did you know that simple machines can help us move loads with less effort? In this example, a simple machine moved a load of 400N through a distance of 10cm when a force of 20N was applied to it. By using the formula for work (force x distance), we can find the input work (20N x 3m = 60Nm) and the output work (400N x 10cm = 40Nm). The AMA (Actual Mechanical Advantage) can be calculated by dividing the output force by the input force (400N / 20N = 20), while the IMA (Ideal Mechanical Advantage) can be found by dividing the distance moved by the force applied (3m / 10cm = 30). To determine the efficiency of the machine, we can divide the output work by the input work (40Nm / 60Nm = 0.67 or 67%). Simple machines allow us to achieve mechanical advantage and increase our efficiency in performing tasks.
