Question

A train wheel has a diameter of 30 in. to the rim, which rests on the track. The flange, which keeps the wheel form slipping off the track, projects 1 in. beyond the rim. When the train is traveling 60 mi/h, what is the linear velocity of a point on the outer edge of the flange?

Answer 4

dan, 30 is diameter, it's just 15

Answer 5

that looks backwards the wheel is 30 and the flange one inch outward at 31? so radius 15 and 15.5?

14.5/15
