A toy car is driven by a torsional spring as shown.
The drive wheel is a 750 gram solid disk 150 mm in
diameter.
The body of the car has a mass of 150
grams, and the mass of the front wheels may be
neglected.
The torsional spring exerts a moment
on the drive wheel of
M = k
θ
where
k
= 0.01 Nm/rad
and
θ
is in radians.
Determine the maximum
speed of the car if is starts from rest with the spring
wound up 8 revolutions.
Assume that the rear
wheel rolls without slip and that the spring
disengages when
θ
= 0 degrees.
