For a motor purchased for a tank project, it claims that at 12v it produces 6000 rpm. this motor is attached to a 50: 1 gear reduction gearbox. the output of this gearbox is attached to a 2.5" wheel. determine the speed of the tank under these conditions in miles/hour (mph).

0.889 mph

Explanation:

Given:

Voltage = 12 V

RPM produced, N₁ = 6000

Gear reduction gearbox, G = 50:1

Diameter of the wheel = 2.5" = 2.5 × 0.0254 = 0.0635 m

Now,

The output speed =  = 120 RPM

Thus,

The speed, v =

on substituting the respective values, we get

v =  

or

v = 0.39878 m/s

Also,

1 m/s =  2.23 mph

thus,

v = 0.39878 × 2.23 = 0.889 mph

energy can cross the boundaries of a closed system in the form of heat and mass

explanation:

d would be the most obvious choice to this question. leaders are supposed to herd their underlings like a shepherd to sheep. a leader should also listen to others when they are talking to one other to gain a better understanding of their mission and surroundings.
