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.

Suppose while hauling rocks, you accidentally drop one. it breaks apart in flat, planar sections. what type of rock did you just drop? 20 points

For the car in the picture ,in which direction is the normal force? -into the screen -down -out of the screen -up

Amass attached to a spring is displaced from its equilibrium position by 5cm and released. the system then oscillates in simple harmonic motion with a period of 1s. if that same mass–spring system is displaced from equilibrium by 10cm instead, what will its period be in this case? a mass attached to a spring is displaced from its equilibrium position by and released. the system then oscillates in simple harmonic motion with a period of . if that same mass–spring system is displaced from equilibrium by instead, what will its period be in this case? a) 0.5sb) 2sc) 1sd) 1.4s
