Answer:
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 = [tex]\frac{N_1}{\textup{G}}=\frac{6000}{50}[/tex] = 120 RPM
Thus,
The speed, v = [tex]\frac{\pi DN_2}{60}[/tex]
on substituting the respective values, we get
v = [tex]\frac{\pi\times0.0635\times120}{60}[/tex]
or
v = 0.39878 m/s
Also,
1 m/s = 2.23 mph
thus,
v = 0.39878 × 2.23 = 0.889 mph
