Final answer:
When riding on grated surfaces, one should be aware of the correct angle to lean into turns to maintain stability by ensuring the bike's forces align with its center of gravity. Increased friction on such surfaces helps prevent slipping, and the use of safety gear is crucial for protection.
Step-by-step explanation:
When riding on grated surfaces such as those designed to increase friction and prevent slippage, it's important to maintain stability and safety. For bicycles, this involves leaning at the correct angle when making a turn to ensure that the force exerted by the ground is on a line going through the center of gravity. This ensures the force exerted by the bicycle wheel has two components: the friction parallel to the road, providing the necessary centripetal force for the turn, and the vertical normal force which balances the system's weight.
Other scenarios where increased friction is beneficial include driving over icy roads with proper tires or using shoes with good grip on slippery surfaces. Not only is physical grip important, but so is wearing appropriate safety gear such as a helmet when bike riding or skating to protect against injury in case of a fal
It's crucial to be aware of the surface's texture and adjust your speed and turning angle accordingly, to maintain control and avoid slipping. Furthermore, taking protective measures such as wearing safety equipment can help prevent injuries when riding on challenging surfaces.
