A Parabolic Bridge Example from a Quadratics Unit in Math

[@PaquiCamus]

My grandson brought up this problem about a parabolic arch under a railway bridge and whether a lorry can go through it. I did have a nice dinner but had to skip dessert. Anyway, your explanation has really put me in the right direction. He is finishing Year 9 Advanced Maths Extension(Australia) and somehow I have become his tutor in Maths and Science. I have subscribed and am going through your videos. Thank you.
