Why is it difficult to hold a school bag having a strap made of thin and strong string

It is difficult to hold a school bag having a thin strap because the pressure on the shoulders is quite large. This is because the pressure is inversely proportional to the surface area on which the force acts. The smaller is the surface area; the larger will be the pressure on the surface. In the case of a thin strap, the contact surface area is very small. Hence, the pressure exerted on the shoulder is very large.

it is difficult to hold a school bag having a thin strap because the pressure on the shoulders is quite large , this is because the pressure is inversely proportional to the surface area , the larger will be the pressure on the surface , in the case of a thin strap the contact surface area is very small Hence the pesseure exerted on the sshoulder is very laarge .

Hint: In this particular question, we will check the dependence of pressure on area. As we know that the pressure is the ratio of force and area. It means that pressure is directly proportional to the force and inversely proportional to the area. \[P \propto \dfrac\]. We also see bags with broad straps, in that case for avoiding the pressure on the shoulders they are made with the broad straps, so that the weight is distributed all over the shoulder and we can lift more stuff for a longer time without feeling so much pain.

We know that : Pressure = `"Force"/"Area"`, when a school bag has a strap made of a thin string, then because Area of this thin string, the weight of a school bag (or force of school bag) will fall on a very small area of the shoulder (or hand) of the child. This will produce a large pressure on the shoulder (or hand) of the child. The large pressure makes it very painful to carry the heavy school bag.

It means that pressure is directly proportional to the force and inversely proportional to the area. \[P \propto \dfrac\].
