Since the heights are the same, then the longer ramp.
The mechanical advantage is 8/2 = 4.
5J because 10/2=5
5/20 = 1/4 or 0.25
1/5 = 0.2
Zero: the ramp cannot be shorter than the height to which it is suppose to reach. I suspect there is a missing decimal point.
The ideal mechanical advantage of the bar is 5.
The ideal mechanical advantage of a ramp is calculated by dividing the length of the ramp by the vertical height. In this case, the ideal mechanical advantage of the ramp is 120m (length) divided by 20m (height) which equals 6. Therefore, the ideal mechanical advantage of the ramp is 6.
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.
A first-class lever can have a mechanical advantage greater than, equal to, or less than 1, depending on the relative distances between the fulcrum, effort force, and load. It does not inherently have a high mechanical advantage.
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 mechanical advantage is 8/2 = 4.
It's 1. IMA = Distance in / Distance out. A single pulley doesn't do anything toward mechanical advantage, it changes the direction of the force. Not always. A single-axeled pulley (the typical pulley) has an IMA of 1, having one axel. If there was a second axel, then the IMA would = 2, so on and so forth. The easy way to do it is IMA = # of axels.
3.3 ft
The ideal mechanical advantage (IMA) of an inclined plane is calculated by dividing the length of the plane by the height. In this case, the IMA would be 8m (length) divided by 2m (height) which equals an IMA of 4.
5J because 10/2=5
The ideal mechanical advantage (IMA) of a ramp is calculated by dividing the length of the ramp by its vertical height. In this case, the IMA would be 3.0 m / 1.0 m = 3.0.
Mechanical advantage measures the ratio of output force to input force, showing how much a machine amplifies force. Efficiency, on the other hand, measures how well a machine uses energy and is the ratio of output work to input work. A high mechanical advantage means a machine can achieve a large force output, while high efficiency means a machine minimizes wasted energy during its operation.
