The given figure shows two shoulder bags, one with a thin strap, and the other with a wide strap. If both bags are equally heavy, the sling bag with the wide strap will be more comfortable to carry because:

The given figure shows two shoulder bags, one with a thin strap, and the other with a wide strap. If both bags are equally heavy, the sling bag with the wide strap will be more comfortable to carry because: Correct Answer the wide strap enables the weight of the bag to be spread over a bigger area, thus reducing the pressure on the shoulder

CONCEPT:

• Force (F): The interaction which after applying on a body changes or try to change the state of rest or state of motion of a body is called force.
  • The SI unit of force is Newton (N)

Force (F) = Mass (m) × acceleration (a)

• Pressure (P): The force per unit area is called pressure.

Pressure (P) = force (F)/area (A)

• The SI unit of pressure is the pascal (Pa) or N/m2.
• The metric unit of pressure is the bar.

​EXPLANATION:

• In the case of a wide strip, the area will be more so the pressure will be less because the force (weight of the bag is the same) is the same in both cases.
• That's why the wide strap enables the weight of the bag to be spread over a bigger area, thus reducing the pressure on the shoulder. Hence option 4 is correct.
