Find the mass moment of inertia of the steel balls used in ball bearings.

Question

4- As part of a highway interchange project, a ramp will be constructed to allow the vehicles exit the first highway and enter the second highway. The first highway runs north-south and the second one had a right angle to the first one (it runs east-west). Vehicles going to the north can use this exit ramp to enter the second highway as shown in the plan view in the figure below. The design speed in both highways is 100 km/hr. The stationing of the start of the horizontal curve is 40+00. a) Determine the stationing of PI and PT¶ b) The first highway has a vertical grade of +3.5% and the second highway has a grade of - 0.5%. The stationing of the beginning and the end of the crest curve are the same as the horizontal curve. What is the elevation of the end of the vertical curve (PVT) if the elevation of the start point (PVC) is 1500m c) Calculate K for the vertical curve Plan view (horizontal alignment) PT 1 N Profile view (vertical alignment) G1=0.5% PVT PC, 40+00 PVC G1=+3.5%
