Link BD is made of brass (E = 105 GPa) and has a cross-sectionalarea of 240 mm2. Link CE is made of aluminum (E = 72 GPa) andhas a cross-sectional area of 300 mm2. Knowing that they support rigidmember ABC, determine the maximum force P that can be appliedvertically at point A if the deflection of A is not to exceed 0.35 mm.

potential energy is directly proportional to height.

more height = more potential energy.

greatest increase in height = greatest increase in potential energy

where are the points with the greatest increase in height ?

has to be c-e or d-e .

b.

explanation:

a.metals can become magnetic if they have many spinning electrons that create magnetic fields.d.only some metals are attracted by magnets; these metals are called ferromagnetic.

d.wrapping an insulated wire around a metal with ferromagnetic properties and applying an electric current.

in physics zero. in muscle fatigue could be high
