Question

The effect of force decreases if it acts over
a larger area.
2. Narrow straps of bags exert less pressure
on the shoulder than the broader straps.
3. The bases of the high-rise buildings are
made wider
4. Skiers use long and flat skis to increase
pressure exerted on the snow.
5. The broad side of a board pin increases
pressure on the thumb.​

Answer 1

Answer:

1. pressure
2. Bags should be provided with broad straps because it decreases the pressureby increasing surface area which makes it easier to carry them. On the other hand,thin straps decrease surface area which results in more pressure and it becomes hard for us to carry them
3. The foundations of high rise building are kept wide so that they exert less pressure on the ground and prevent thebuilding from sinking into the ground
4. Skiers use flat and long skiers to slide onsnow,because the larger the area of cross-section,the lesser is the pressureon snow.
