Question

(18) With neat diagrams, describe an experiment to show that pressure increases if the surface area is
decreased, keeping the applied force the same. [HOTS]
Ans.​

Answer 1

Answer:

Explanation:

Take yourself and stand barefoot and flatfooted on one leg on the floor. For the sake of discussion, the area of your heel is 100 square centimeters. Now put on a weightless shoe with a “spike” heel. It has an area of 1 square centimeter. In both cases is your weight pressing down on each heel the same? No snacking or drinking during this experiment. Ok, is the area of each heel the same? What is pressure? It the ratio of force (in this case your weight) to the area impacted by the force. Can you see how the same force can have a decidedly different result by changing the area. Back in olden times, when women would wear extreme spike heels to dance on wooden floors, they were given small pads to attach to their heels to increase the area of the heel so that it would not poke holes in the floor.
