Question

There are $15$ radial spokes in a wheel, all equally inclined to one another. Then there are two spokes which

• A. lie along a diameter of wheel
• B. are perpendicular to each other
• C. are inclined at angle of ${24}^o$
• D. inclined angle less then ${24}^o$

Answer 1

The correct option is C are inclined at angle of ${24}^o$

The angle between two consecutive spokes will be given by the total degrees(360) divided by the number of spokes.

$\frac{2\pi }{spokes}=\frac{360}{15}={24}^o$

The angle between a pair of two consecutive spokes $={24}^o$
