Answer:11.602 KW
Explanation:
mass of vehicle
speed=40Km/h
Resistance=600 N
Gear ratio
Net force to overcome by engine is
F=Resistance + sin component of weight
F=600+
Where
F=600+235.38=835.38 N
power=
Engine Power==11.602 KW
Answer:
The lumped body analysis is most applicable for slender bodies because Biot number is smaller for the slender bodies as compare to the well rounded bodies.
As we know that Biot number Bi ,given as
h= heat transfer coefficient
k= thermal conductivity
Lc=characteristic length
V=volume
A=area
When Bi is less than 0.1 then lumped body analysis is applicable.
