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.

a lot of it means it can be "burned" for energy and sold at one price. if it is scarce, the price will go up

no

sodium is solid at rt

note: the given question is incomplete.

complete question is given below.

which is an example of kinetic energy?

a. the energy stored in ethanol  

b. a hockey puck sliding across the ice  

c. a compressed spring  

d. a ball sitting at the top of a ramp

solution: the kinetic energy is the energy posses by the virtue of the motion of the object.

in the given options, a, c and d are the example of potential energy because it is the energy posses by the virtue of the rest of the object. but option b has the kinetic energy as the object is in motion.

hence, a hockey puck sliding across the ice   is the apex example of kinetic energy.

so, the option (b) a hockey puck sliding across the ice   is the correct option.

you get 2.3=1.21*\frac{a}2 or 4.6=1.21a or a=3.802 (b)
