Rotational dynamics

VITEEE 2015 Forum › Mechanics questions › Rotational dynamics

Imagine a two wheeled robot as shown in the figure here. The robot has two DC motors with rated speed of 60 rpm. The distance between the two wheels is around 20 cm. What should be the operating speeds of both the motors (outer and inner), such that the inner wheel covers a circle of 40 cm radius (as shown) in fastest possible time?

The question is really good..

Try this...

The angular velocity should be equal from the center for the car...

for both the tyres...

so v1/r1=v2/r2 where the v1 is the higher velocity and r1 is the outer radius..

yeah sir its true !

but "the fastest possible time"

with tis ratio there can be many answers na ?
