Question

There are 2 carry bags A & B. Bag A is provided with a broader strap while bag B is provided with a thinner strap. For the same load, Amar likes bag A as he is comfortable holding it on his shoulders, but with bag B he develops a pain on his shoulders. Choose the correct option

• A. Due to the thinner strap the pressure developed is more for the same load than bag A
• B. Due to the broader strap the pressure developed is less for the same load than bag B
• C. Pressure is defined as force per unit area
• D. All of these

Answer 1

The correct option is D

All of these

Since, pressure is defined as force per unit area therefore, for the same load pressure developed would be more in the bag with a lesser contact area. SO, since bag B has a thinner strap than bag A therefore, the pressure developed is more in bag B than bag A for the same load.
