1.	Calculate the velocity of the bottom point of the wheel for perfect rolling using the data: r=20 cm, ω=100 rad/sec.(a) 20 m/sec(b) 40 m/sec(c) 60 m/sec(d) 80 m/secI have been asked this question in an interview for internship.This interesting question is from Nature of Traction Load in division Traction Drives of Electric Drives
Answer» Correct option is (a) 20 m/sec Explanation: The velocity of the bottom point of the wheel for perfect ROLLING is the product of the RADIUS and ANGULAR velocity. It is expressed in terms of m/sec. V = r×ω = .2×100=20 m/sec.
