What is the standard geometric shape of a hurdle_________________?
Show answer Hide answer
Answer: C. L
Explanation
Track hurdles are designed in an L-shape profile so they tip over. This specific geometry ensures that runners do not suffer injuries upon impact. The weighted base keeps the hurdle upright until struck with sufficient force. Hurdle engineering has evolved significantly to prioritize runner safety. The L-shape allows the barrier to rotate forward and fall flat when hit. Modern materials provide durability while maintaining the required safety profile.
Manufacturers construct track hurdles to meet international safety certifications. Athletes practice hitting hurdles with their lead legs without fearing injury. Track officials adjust hurdle weights carefully based on race age categories. U shape does not describe the folding profile of a standard track hurdle. H shape is incorrect because the side profile forms a distinct letter L. V shape fails to match the weighted base and upright bar design of hurdles.
