it is the ratio of the velocity of the point of application of effort to the velocity of the load

To find the velocity ratio of a pulley, you must first find the effort and load distances. then you divide the two and there you have you VR (velocity ratio).

No. The velocity ratio remains constant but the friction absorbs power.

When the second element of the ratio is 1.

The ratio of Mechanical Advantage and Velocity Ratio is Efficiency. That is to say the ratio of M.A. and V.R. is constant.

The relationship between mechanical advantage, velocity ratio & efficiency is:- efficiency=Mechanical Advantage/Velocity Ratio

acceleration=ratio of change in velocity in a specific direction to time. speed=ratio of distance to time.

average velocity means change in displacement and time interval ratio is called as average velocity average velocity what is the velocity at particular instant of time

Average velocity is def.ined as the ratio of total displacement to total time taken.

Ratio of change of velocity to the time

Define these Levels of Measurement.NominalOrdinalInterval/Ratio

The ratio of provision against total NPA

Higher the viscosity then velocity gradient would be higher. Velocity gradient is the ratio of change of velocity to the distance between the layers of the liquid

The size of velocity and the size of speed are the same number. But velocity also has a direction and speed doesn't.

The ratio for a simple pulley (not a pulley block), using an inelastic string, is 1.

Effort force:Load force. For example, if you put in 10 newtons of force and the load force was exerting 5 newtons the velocity ratio would be 2:1

Refractive index refers to the velocity of light's ratio in a vacuum to its velocity under a specified medium.

swirl ratio = air rotational speed / crank shaft speed of an ic engine

When equivalence ratio increase, the actual air-fuel ratio decrease, which mean the mass flow rate of air is decrease. So, the volume flow rate of air is dercreasing and its mean the velocity is decreasing.

efficiency is defined as the concept of mechanical advantage and velocity ratio.

It can be calculated by the following two formulas:- 1) VR = Velocity of effort/ Velocity of load. 2) VR = distance of effort / distance of load.

the ratio of death in an area to the population of the area

Mass by itself has no effect on velocity. In terminal velocity (velocity of an object falling through a fluid) the mass tovolume ratio (density) can change the final velocity at any given medium density, but in acceleration in a vacuum there is no impact from mass on velocity.

Frequency is the parameter of light which doesnt change on reflection because it is the ratio of velocity of light in medium and wavelength of the particle.Hence,when velocity increases wavelength also increases and when velocity decreases wavelength also decreases but its ratio always remains constant.
