Question

The wheel in Fig.10-30 has eight equally spaced spokes and a radius of 30 cm. It is mounted on a fixed axle and is spinning at 2.5 rev/s. You want to shoot a 20-cm-long arrow parallel to this axle and through the wheel without hitting any of the spokes. Assume that the arrow and the spokes are very thin. (a) What minimum speed must the arrow have (b) Does it matter where between the axle and rim of the wheel you aim If so, What is the best location

Q5
A wheel has eight equally spaced, very thin spokes of length 30 cm. It is rotating about an axis OO' which is perpendicular to its plane and passing through the centre, with 2.5 rps. We want to pass a 20 cm long arrow parallel to the axis and without hitting any spoke. What should be the minimum horizontal velocity of the arrow?
