Question: Q: What is the effect on pressure when the area of applied force is very concentrated? Read this paragraph and choose the correct option from the provided answers: Pressure shows how concentrated the force is on a given area. The smaller the area to which force is applied, the greater the pressure is. Think about pressing a pushpin, like the one in Figure below , into a bulletin board. You apply force with your thumb to the broad head of the pushpin. However, the force that the pushpin applies to the bulletin board acts only over the tiny point of the pin. This is a much smaller area, so the pressure the point applies to the bulletin board is much greater than the pressure you apply with you thumb. As a result, the pin penetrates the bulletin board with ease. Choices: - direction increases - pressure disperses - pressure reduces - pressure increases A:
Answer: pressure increases
