The tradeoff for the increased force exerted by a simple machine is that you have to apply the force over a longer distance. The mechanical advantage of the machine boils down to the ratio of distance you apply a force to the distance the machine applies the force, and the latter must be...
The longer and sharper a wedge is, the less effort it will take for the work to get done. A shorter wedge will require more force and effort because it has a wider angle at the tip. The mechanical advantage (the amount of force used) will be higher with a long wedge having a thinne...
Is an inclined plane a simple machine? A lever is used to lift a fallen tree that has a weight of 485 N. If the lever has a mechanical advantage of 6, what force must be applied to lift the tree off the ground? How is a screw like an inclined plane?

The power of the wedge can be measured in terms of its mechanical advantage, and it is calculated by dividing the wedge’s slope by its width. A more narrow, or acute, wedge angle has greater mechanical advantage, particularly when it is made of steel or iron. The power of the wedge,...
I will bias the balance forward slightly so as to always have weight/pressure on the gear teeth in the Mount . Then as the Mount advances over the imaging Session it will always be putting a positive pressure back onto the mechanical system and greatly reduce any slop between the gear train...

and a compact structure is also provided. The system thus allows for application of the mechanical advantage offered by the wedges in movement of the ram relative to the bed. The placement of the actuator between the wedges further allows for lack of congestion about the ends of the machine....
This is a substantial proportion of the total torque output of the machine, amounting to as much as 80-85% of the total torque output, and it relieves the mechanical components of some of the stresses that they would otherwise have to carry to generate the same total torque output without ...
A further object of the invention is to provide an assembly which is efficient in operation, simple in construction, and relatively inexpensive to manufacture. Another object of the invention is to provide a relatively small mechanical advantage in the direction of lift on a workpiece supported on...
