Effort of 80N applied to a machine was moved through a distance of 25cm to cause a load to move a distance of 3. 8m Calculate the velocity ratio of the system
To calculate the velocity ratio of the system, we need to first understand the concept of velocity ratio.
Velocity ratio is the ratio of the distance moved by the effort to the distance moved by the load. It is a measure of how much the system amplifies or reduces the input force.
In this case, the effort force applied to the machine is 80N and it moves through a distance of 25cm. The load is moved a distance of 3.8m.
The velocity ratio (VR) is given by the equation:
VR = Distance moved by effort / Distance moved by load
Distance moved by effort = 25cm = 0.25m
Distance moved by load = 3.8m
VR = 0.25m / 3.8m
VR = 0.0658
Therefore, the velocity ratio of the system is approximately 0.0658.
