Expert Answer:

1. The edge of knife is made sharp so that with little force it cuts better. This is because, on sharpening the knife the area reduces, and hence the pressure increases.
2. Foundation of dams and building are made on large surface area so as to decrease the effect of force by increasing area on which it acts. Thus, pressure is reduced.
