Ascientist has a sample of uranium–238 (u–238) that is decaying to thorium–234 (th–234). during the transmutation, a gamma ray is emitted from the nucleus. the thorium–234 daughter particle does not decay quickly enough to be detected. what kind of storage container should he store the sample in to reduce radiation exposure?

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.
