The ‘London Eye’ can be considered to be a circular frame of radius 67.5m on the
circumference of which are ‘capsules’ carrying a number of people round the circle. Take
a co-ordinate system where O is the base of the circle and Oy is a diameter. At any time
after starting off round the frame, the capsule will be at height h metres when it has
rotated .°θ
Apparently answer is... 67.5(1-Cosθ)??? why?
Thanks
