WebAs shown in the figure, the ideal mechanical advantage is calculated by dividing the radius of the wheel by the radius of the axle. Any crank-operated device is an example of a wheel and axle. Figure 9.9 Force applied to a wheel exerts a force on its axle. An inclined plane …
WebThe three different types of lever are: First class lever Second class lever Third class lever Give some examples of second class levers. Give some examples of second class levers. Wheelbarrow, staplers, doors or gates, … WebMechanical advantage: Second class levers allow a large load to be moved with a relatively small amount of muscular effort. Is the mechanical advantage of a 2nd class lever greater or less than 1? Second class lever has mechanical advantage always more than one as load is in between fulcrum and effort making the effort arm longer than the load arm.
