If I get the correct answers to the following problems, ill be giving gearz on useast nl or ladd.
A curve of radius 80 m is banked for a design speed of 60 km/h. If the coefficient of static friction is 0.30 (wet pavement), at what range of speeds can a car safely make the curve?
Find Maximum and Minimum Speeds in KM/HR.
Equations:
Force of Friction = Coefficient of Static Friction times Mass times Gravity (9.8m/s2)
Coefficient of Friction times Gravity Equals Velocity squared divided by Radius
Trigonometric Functions i.e. Sin, Cos, Tan...
A car at the Indianapolis-500 accelerates uniformly from the pit area, going from rest to 305 km/h in a semicircular arc with a radius of 196 m.
Determine the tangential acceleration of the car when it is halfway through the turn, assuming constant tangential acceleration.
Determine the radial acceleration of the car at this time.
If the curve were flat, what would the coefficient of static friction have to be between the tires and the roadbed to provide this acceleration with no slipping or skidding?
Equations:
Centripital Force = Mass times Acceleration
Centripital Acceleration = Velocity2/radius
Pi times D = Circumference
D= 2*r
2*pi*r*Frequency= V
Frequency= Revolutions per second
If the last one is completely correct, ill add in several awesome items imo.
