KCET case studies
KCET · Put your knowledge to work in context.
KCET (Karnataka Common Entrance Test), also called Karnataka UGCET, is the state-level entrance examination used for admission to undergraduate professional programmes in Karnataka, notably engineering, pharmacy, agriculture and veterinary courses in participating government, aided and private institutions. It is aimed at students who have completed or are completing the second-year pre-university course (or an equivalent 10+2 qualification) with Physics, Chemistry and Mathematics and/or Biology, and who want a state merit rank rather than relying solely on national-level tests. The KCET case studies are 5 cases and about 3,731 words.
1Banking, Friction and the Safe Speed Window on a Hill Curve
A 100 m radius highway curve on a hill road near Chikmagalur is banked at 15°; tan 15° = 0.268, sin 15° = 0.259 and cos 15° = 0.966. Tyre tests give a coefficient of static friction of 0.40 on dry asphalt and 0.25 when the surface is wet, and g may be taken as 10 m/s².
