The towers of most suspension bridges are made of steel, although a few have been built of steel-reinforced concrete.
to be honest i dont know but i need some points so people can help me with my test.
I'm an amateur at digital art, so my suggestion may not be as useful to you. I suggest using the RCA Cambio, It's 32GB and comes with Paint 3D. It's also a laptop/tablet hybrid, so it's good for other things too. I got it at the affordable price of $120 at Staples
Thanks!
