What is the mechanical advantage of a machine without friction?
Machinal advantage, also known as mechanical advantage, refers to the ratio of the force produced by a machine to the force applied to it. A machine can be useful even its machinal advantage is less than 1.
How do you fix a short circuit in a pulley system?
Short circuits are typically associated with electrical circuits. Pulley systems are associated with mechanical cable and pulley lifting systems. The two are so different that the question does not make sense. Please restate the question.
Why is it easier to pull out a nail with a long-hammer than with a short-handled hammer?
the long handle provides a greater lever effect
What are the examples of advantages?
I'm not sure how this is related to science and technology, so I'm gonna give a general answer. Being tall when you need to reach something that's out of reach of short people is an advantage. Having a torch or a lighter when you're in dark area is an advantage. Having a cellphone/compass/map with you when you're alone in a forest is an advantage. Hope that helps :P
What is the primary advantage of PEX pipe?
There are too many:CostFlexibilityResistance to corrosionLess fittingsBetter resistance to freezingComes in continuous coils rather than 10ft short piecesLightweightEasier to install than copper and CPVC
Would a short or long ramp have a greater mechanical advantage?
There is a mechanical advantage in using a long, gently sloping ramp than a short steep ramp. If you want to test this remember what goes up must come down and a long ramp gives you more time to react

What advantage is there to making graduated cylinders narrow and tall rather than short and wide?
Greater accuracy in reading them.
Which has a greater mechianical advantage short ramp and a long ramp both reach a height of 1m?
The long ramp.
Does a long gently sloped inclined plane or a short steep inclined plane have the greatest mechanical advantage?
Long gently slope inclined plane
What are the short term professional courses after mechanical engineering?
short term course after be mechanical
Can Mechanical Advantage be greater than Velocity Ratio for any machine?
Sure, take your forearm, for instance. It is a lever that trades force for speed because the insertion points for the muscles on the bone (effort) are closer to the fulcrum (elbow) than the resistance (your hand). Your muscle contracts a short distance but that is translated to a greater distance at the hand. A short effort arm and a longer resistance arm gives a lever with a MA < 1
Is a toilet flusher a lever?
Yes, but it sort of works in reverse. You usually use a lever to gain a mechanical advantage by having the load on the short end and applying pressure to the long end. The short end of the flush lever is pushed down a short distance and other end goes up a longer distance, giving you an advantage in distance.
Why does a longer bicycle ramp have better mechanical advantage than a shorter one?
Mechanical advantage is defined as the input force divided by the output force. If both ramps have the same final height, the longer one will generally have the greater mechanical advantage because it requires less overall work from the cyclist to raise the bicycle to a higher potential energy in a uniform gravitational field. The limit to this exists where the ramp becomes so long that it actually takes more energy to traverse than the short since you must account for the work required to maintain forward motion against friction and the climb against gravity. This limiting distance is related to the final height of the ramp.
What factors determine the mechanical advantage of pulley system?
Disregarding friction and other losses, mechanical advantage N = F/f which is force into the system f and force out F. We can think of each wheel in a pulley system as being part of a lever. And each lever has its own mechanical advantage n = F/f = L/l where L is the long end from the fulcrum and l is the short end from it. And there we are. Those lengths, L and l, have their analogs in the pulley wheel radii or diameters (they are equivalent). So if you have a pulley system made up of two connected wheels, with diameters D and d, the mechanical advantage of the system is N = D/d or R/r for radii. If there are more than two wheels, we can simply multiply the mechanical advantages between each pair of connected wheels to get the total mechanical advantage of the entire system.
Can a machine be useful if its mechanical advantage is less than one?
Sure, take your forearm, for instance. It is a lever that trades force for speed because the insertion points for the muscles on the bone (effort) are closer to the fulcrum (elbow) than the resistance (your hand). Your muscle contracts a short distance but that is translated to a greater distance at the hand. A short effort arm and a longer resistance arm gives a lever with a MA < 1
That kid has bad spelling?
Theoretically, wedge is a simple machine that is used to offer mechanical advantage. The force normal to inclined surfaces of wedge is much greater(depending on angle of wedge) than force applied to the short side. This is exploited in axes and various other tools. ALL OF THIS IS WRONG!q!!!!!!!!!!!!!!!!!!!!! ASK YUR TEECHAR
