Short Answer
Advertisements
Solution
- We know that pressure is equal to force divided by area. When the school bag's string is thin, its area is small, resulting in increased pressure on the shoulders or hands supporting the bag.
- In this situation, the force applied to the shoulders or hands that support the bag is equal to the weight of the bag.
- If the strap is wide, as it normally is, the area on which the force (weight of the bag) operates is big, and the pressure is lessened because the weight of the bag is now distributed over a broader area.
