Part of the formula for measuring velocity comes from isaac newton's second law of motion which states that f=ma.

Velocity ratio formula. Where, v = velocity ratio. Velocity (v) is equal to the ratio of change in position (δx) to the time (t).using the formula of velocity: The motion ratio of a mechanism is the ratio of the displacement of the point of interest to that of another point.

L = distance moved by the load. Since we convey displacement in meters and time taken in. Now put the values in the formula.

You can also use an alternative inventory velocity formula (but companies typically go with the first one): Velocity ratio is the ratio of the distance moved by the point at which the effort is applied in a simple machine to the distance moved by the point at which the load is applied, in. Gear ratio can be worked out in the form of numbers and.

The diagram opposite shows a small driver pulley pulling round a larger driven pulley. We ‘pay’ for being able to raise a large load by applying effort over a. Calculate the efficiency (%) of the machine.

Number of units sold / average number of units on hand. This means multiplying an object’s acceleration by its mass. V = a / t.

Where, s = displacement, t = time taken. The most common example is in a vehicle's suspension, where it is used to. The rpm (revolutions per minute) of the larger driven pulley.
