Why is it difficult to ride a bicycle against the wind class 7?
We find it very difficult to ride a bicycle against the direction of wind. This is because in this case the blowing wind exerts a force on us in the direction opposite to the motion of our bicycle. And since the wind opposes our motion, we have to pedal very hard to keep the bicycle moving against the wind.
Why is it difficult to ride a bicycle while moving against the wind class7?
Ans. It is difficult to ride a bicycle against the direction of wind because in this case, the blowing wind exerts a pressure on us in the opposite direction in which our bicycle is moving. So, the wind blows in opposite direction to the motion of the object, it makes the movement of the object difficult.
Why do umbrellas break so easily?
Umbrellas suffer from a variety of injuries during the rainy season. First off, the metal ribs that hold the umbrella fabric in place aren’t always strong enough. They’re joined with intricate metal parts that have to handle a lot of grief from the elements. It doesn’t take much for things to strain and break apart.
Are cantilever umbrellas better for wind?
A great choice for wind-resistance is a cantilever umbrella, which is suspended and supported by a support rod placed to one side rather than in the middle of the canopy. The unique design imparts strength, stability, safety and versatility.
Why do umbrellas flip inside out?
For an umbrella, it is very important to be able to close back, it is a guarantee of quality and resistance against the wind. The ribs of an umbrella must be flexible and the joints quite solid to allow the umbrella to flip back in case of strong gusts of wind, instead of it fully breaking.

Why are roofs blown off when there is a strong wind class 7?
The pressure below the roof is equal to the atmospheric pressure which is now larger than pressure above the roof. This difference of pressure causes an upward thrust and the roof is lifted up. Once the roof is lifted up, it is blown off with the wind along its direction.
