A machine raises a load to 2m,when the efforts moved by 8m. What is velocity ratio of machine

Do you have answer choices?
if 100% efficient then 60 *2/8 = 60/4 = 15 N
it actually took you 20 N
100 * 15/20 = 5*15 = 75%
A certain machine has an efficiency of 80%. If the load moves a distance of 2m as the effort moves 8m, how large a force is required to lift a load of 320 New ton?
The mechanical advantage of a simple machine is 4.the machine lifts load of 1000 New Ton. What is the force that act's on the machine?
To find the velocity ratio of a machine, we need to know the distance moved by the effort and the distance moved by the load.
The velocity ratio (VR) is calculated using the formula:
VR = Distance Moved by Effort / Distance Moved by Load
In this case, we are given that the effort moves by 8m and the load is raised to a height of 2m.
Since the load is being raised vertically, the distance moved by the load is equal to the height it is raised, which is 2m. The distance moved by the effort is given as 8m.
Now we can use these values to calculate the velocity ratio:
VR = 8m / 2m
Simplifying this equation gives us:
VR = 4
Therefore, the velocity ratio of the machine is 4.
