A man exerts an effort of 250 Newtons through a distance of 4 meters to lift a load of 1000 Newtons through a height of 0.75 meters. Calculate the velocity ratio.
I'm thinking i divide the 4 meters(displacement of effort)/0.75 meters (displacement of load)
To calculate the velocity ratio, you need to compare the displacement of the effort to the displacement of the load. However, it's important to note that the units of displacement should be the same when making this comparison.
In this case, the displacement of the effort is given as 4 meters, and the displacement of the load is given as 0.75 meters. Since the load is being lifted vertically, the displacement of the effort and the displacement of the load are in the same direction, and there is no need to consider any trigonometric relationships.
To calculate the velocity ratio, divide the displacement of the effort by the displacement of the load:
Velocity Ratio = Displacement of Effort / Displacement of Load
= 4 meters / 0.75 meters
= 5.33
Therefore, the velocity ratio is approximately 5.33.
