Hanging Spring When a 0.30 kg mass is suspended from a massless spring, the spring stretches a
distance of 2.0 cm.
Let 2.0 cm be the rest position for the mass-spring system.
The mass is then pulled down an additional distance of 1.5 cm and released.

Calculate the total mechanical energy of the system in SI units.

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.
