5/20 = 1/4 or 0.25
1/5 = 0.2
To nearly its original high
Yes
The mechanical advantage is 8/2 = 4.
The exact answer of 8m/2m = 4 meters high. Thank you.
1/5 = 0.2
it really depends on the machine you are talking about. there are 6 simple machines: the lever, wheel and axle, pulley, inclined plane, wedge, and the screw. Lever = (distance from fulcrum to effort) divided by (distance from fulcrum to resistance) Wheel and Axle = (diameter of the wheel) divided by (diameter of the axle) Pulleys = the # of pulleys used Inclined Plane and Wedge = (length of slope) divided by (height) Screw = (circumference) divided by (pitch) Hope this helped :)

Mechanical advantage is maximum when weight lifted is extremly high and for which C/W is extremely small so as to be negleted, Max. Mechanical Advantage=1/m
The ideal mechanical advantage of the bar is 5.
The mechanical advantage is 8/2 = 4.
3.0 m
It may be good in some cases. A high mechanical advantage comes at a cost - you need to apply less force, but you need to apply it over a greater distance.
