Researchers have found that a gecko’s foot iscovered with hundreds of thousands of small hairs (setae) thatallow it to walk up walls and even across ceilings. A single foot pad,which has an area of 1.0 cm2, can attach to a wall or ceiling with aforce of 11 N. (a) How many 250-g geckos could be suspended fromthe ceiling by a single foot pad? (b) Estimate the force per squarecentimeter that your body exerts on the soles of your shoes, andcompare with the 11 N>cm2 of the sticky gecko foot.

Question
Researchers have found that a gecko’s foot is
covered with hundreds of thousands of small hairs (setae) that
allow it to walk up walls and even across ceilings. A single foot pad,
which has an area of 1.0 cm2, can attach to a wall or ceiling with a
force of 11 N. (a) How many 250-g geckos could be suspended from
the ceiling by a single foot pad? (b) Estimate the force per square
centimeter that your body exerts on the soles of your shoes, and
compare with the 11 N>cm2 of the sticky gecko foot.
