A lever is one type of machine that gives you a mechanical advantage. A seesaw is an example of a lever. The part that holds the seesaw off the ground is called the fulcrum. Using the lever and fulcrum, you can lift things that would otherwise be too heavy. ...
What is its mechanical advantage? View Solution Q3 In a machine, an effort of 10 kgf is applied to lift a load of100 Kgf. What is the mechanical advantage of the machine? View Solution Q4 Determine the mechanical advantage of a simple machine which helps to lift a load of 75 kgf...
Wheel and axle: A wheel is essentially a lever with one arm the distance between the axle and the outer point of the wheel, and the other the radius of the axle. Typically this is a fairly large difference, leading to a proportionately large mechanical advantage. This allows even simple wh...
These are devices that use mechanical advantage to multiply force, rendering the work to be done in more efficient manner and a higher quality output. Examples of such devices are inclined planes, levers, wedges, wheel and axles, pulleys, and screws. ...
