A 25 g object is pressed against a spring causing the spring to compress 5 cm. the spring constant is 300 N/m.
if the object moves vertically when released, what is the maximum height the object will reach?
what maximum height will the box reach if 0.1 j of energy is lost due to air resistance?
the spring is turned horizontally, and the same object is used to compress the spring by the same amount. if friction is negligible, what is the speed of the object when the spring is released?
how much force did it take to compress the spring?

The rigid beam is supported by the three suspender bars. bars ab and ef are made of aluminum and bar cd is made of steel. if each bar has a cross-sectional area of 450 mm2, determine the maximum value of p if the allowable stress is (σallow)st = 200 mpa for the steel and ( σallow)al = 150 mpa for the aluminum. est = 200 gpa and eal = 70 gpa.
