Knowing that a force p of magnitude 50 kn is required to punch a hole of diameter d = 20 mm in an aluminum sheet of thickness t = 5 mm, determine the average shearing stress in the aluminum at failure.

find the surface area of the sphere to the nearest square unit. use a calculator.

a. 254 in.2

b. 64 in.2

c. 127 in.2

d. 1,018 in.2

+15-35=-20

going in opposite directions

distance = 150m

displ = root (50 ^2 + 100^2)

root(2500+10000)

root 125000
