So, Amit stared doing it by stretching the palms on the floor while Sumit opted to do the same job on pair of rods at some height from floor. Amit got less pain as compared to Sumit because ​

Answer 1

Answer:

Now here Amit was in contact with the floor and their friction between the floor And his palms.

Explanation:

Amit had lesser pain compared to that of sumit as amit used the idea of doing the dips by streching his palms on the floors. Now here Amit was in contact with the floor and their friction between the floor And his palms. So he had floor as his support and he had not to apply that much effort .

On the other hand sumit applied more effort as he had no support and thus his hand was paining.

Answer 2

Amit got less pain compared to Sumit because:

• Amit exerted force directly onto the floor which does not require much pressure from his body and the friction on the plane surface like the floor is good.
• Whereas Sumit used rods, which is not a plane surface, in this case, the pressure exerted would be double.
• Sumit would lose grip and he would lose his balance as there is no contact between the ground.
• Friction on any other surface except the plane surface is less because of less surface area and uneven distribution of force.
