Variables Used

Translational Speed - (Measured in Meter per Second) - Translational Speed is the speed of the center of a wheel with respect to the ground. It is also called as linear speed.
Effective Radius of Wheel - (Measured in Meter) - The Effective Radius of Wheel is the radius of the part of the wheel which remains undeformed while rolling.
Speed of Motor Shaft in Powerplant - (Measured in Revolution per Minute) - Speed of Motor Shaft in Powerplant (Engine or Motor or combination of both) is the rotational speed with which the motor shaft or crankshaft (in case of engine) rotates.
Gear Ratio of Transmission - Gear Ratio of Transmission is the ratio between the revolutions of the engine crankshaft and the revolutions of the shaft which comes out of the gearbox.
Gear Ratio of Final Drive - Gear Ratio of Final Drive is the ratio between the revolutions of the gearbox shaft and the revolutions of the wheels.

STEP 1: Convert Input(s) to Base Unit

Effective Radius of Wheel: 0.45 Meter --> 0.45 Meter No Conversion Required
Speed of Motor Shaft in Powerplant: 4879 Revolution per Minute --> 4879 Revolution per Minute No Conversion Required
Gear Ratio of Transmission: 2.55 --> No Conversion Required
Gear Ratio of Final Drive: 2 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

V_t = (pi*r_d*N_pp)/(30*i*i_o) --> (pi*0.45*4879)/(30*2.55*2)

Evaluating ... ...

Difference between Rotational and Translational motion?

Translational Motion: Translational motion is motion that involves the sliding of an object in one or more of the three dimensions: x, y or z. But an object can still be moving even when it's just sitting at a particular x-, y- and z-coordinate, it can still spin.
Rotational Motion: Rotational motion is where an object spins around an internal axis in a continuous way. An ice-skater can do this by spinning on the spot. She will give herself rotational energy. And because energy is always conserved and a smaller object must spin faster to have the same energy, when she moves her arms in towards her body, her rotation speed will increase - the spinning will get faster and faster.
