Question on: JAMB Physics - 2024
If the velocity ratio of a machine is 4, what does it mean?
A
Load and the effort are equal.
B
Distance moved by effort is 4 times greater than the distance moved by load.
C
The efficiency is low
D
The load is greater than the effort
Ask EduPadi AI for a detailed answer
Correct Option: B
The velocity ratio (VR) of a machine is defined as the ratio of the distance moved by the effort to the distance moved by the load. A VR of 4 means that for every unit distance the load moves, the effort moves 4 units.
