K, so we have this insane teacher (Mr. Hisey) we have to work on researching skills and get the answer to certain stuff from a real person rather than just a website. so here it goes...Question: How do the frame and wheels of a bike keep it from collapsing under the weight of a person? And do bikes always having triangles in the frame have anything to do with it. If anyone knows PLEASE help me. I need this for tomorrow, so I need the answer tonight. THANK YOU SO MUCH!!! -herBert
