Detailed Solution

School bags are provided with wide straps. This helps to reduce pressure on shoulders.
From the definition of pressure, we know that force working on a unit area is called pressure. It is directly proportional to the force and inversely proportional to the surface area on which force acts. So, school bags are provided with wide straps because it helps to reduce pressure on shoulders as the area of contact of big straps is more; therefore, the pressure exerted on the shoulder is decreased.
