You would have to lift a given mass (m) a certain distance(h) and work out the amount of energy(work) this has taken using W=mgh, where g is acceleration due to gravity. Then you would have to use a torque metre to wind the jack , and using the number of turns needed to lift the weight, calculate the amount of work done, using E= torque x angle travelled(in radians). In an ideal frictionless jack the two figures would be the same. The difference between the two is the amount of energy lost to friction.The mechanical advantage you mention is related to the pitch of the screw or thread.That is,a fine thread pitch can lift more weight using only human force, but with a greater number of turns.I should also mention that in a diamond shaped,lever type jack, the mechanical advantage increases, and the torque required decreases, the higher the jack is extended. It becomes a little more complicated, involving vectors, angles, and maybe even calculus. Perhaps another poster could help here.

How do you find the mechanical advantage of wheel and axle?
you have to divide idk * * * * * You can find the ideal mechanical advantage of a wheel and axle by dividing the radius of the wheel by the radius of the axle.
What is a example of mechanical efficiency?
A very practical example of mechanical advantage is the use of a "cheater bar." If you find a bolt that is hard to break, simply slip a long pipe or similar object over the handle and it will apply much more torque.
How do you find the mechanical advantage of a ramp?
The mechanical advantage of a ramp is calculated by dividing the length of the ramp by the vertical rise. This ratio represents how much less force is required to move an object up the ramp compared to lifting it straight up. The formula for mechanical advantage of a ramp is: Mechanical Advantage = Length of ramp / Vertical rise.
You test a machine and find that it exerts a force of 5 N for each 1 N of force you exert operating the machine What is the actual mechanical advantage of the machine?
The mechanical advantage is 5.Mechanical Advantage = Output Force/Input Force
How do you find output force?
Output force can be found by multiplying the input force by the mechanical advantage of a machine. The mechanical advantage is the factor by which a machine multiplies the input force to generate the output force. The formula for calculating mechanical advantage is output force/input force.
What is the formula to find mechanical advantage?
The mechanical advantage that a machine would have without friction or in another term is that you can find the IDEAL MECHANICAL ADVANTAGE (IMA) OF A MACHINE IS BY HAVING A MACHINE WITH NO FRICTION, ALSO BY MULTIPLYING YOUR EFFORT FORCE BY 2, HOWEVER BECAUSE OF FRICTION AND THE WEIGHT THE ACTUAL MA WILL BE LESS.

How do you find the mechanical advantage in science?
mechanical advantage= output force over input force
Why does a fixed pulley have a mechanical advantage of one and a movable pulley has a mechanical advantage of two?
we find mechanical advantage of pulley by using principle of lever. according to this moment of effort is equal to moment of moment of load. As in this case effort arm is equal to load arm. so mechanical advantage is equal to one. but we know we can never finish friction between rope used and pulley so mechanical advantage is less than one
Why do you multiply to find the total mechanical advantage?
The "Ideal Mechanical Advantage" of a simple machine isIMA = output force /input force . To find the 'actual' or real-world mechanical advantage,multiply the IMA by the machine's efficiency.
