Question
100%
The radius of a highway-curve is 120m, and has an angle of
9.31 from the horizontal. The center of gravity of the truck is
located 0.80m above the roadway and the distance between
the two front wheels is 1.2m. If the truck has a total weight of
15KN,
a. Determine the normal acceleration (m/s2) and the
velocity (in kph) of the truck before overturning (*Note
that friction is neglected between the tires and the
road)?
b. Find the maximum velocity of the truck could move in
the curve so that there will be no pressure between the
tires and the roadway.
c. If the allowable speed of the highway curve is 80 kph
and the coefficient of kinetic friction is 0.60, what is the
velocity of the truck without sliding?
