Two 14-month-olds are observed in the Strange Situation. Infant A explores the playroom freely while using her mother as a base, shows mild distress when her mother leaves, and quickly seeks out and is soothed by her mother at reunion. Infant B stays close to his mother and explores little, becomes very upset when she leaves, and at reunion both reaches for her and angrily pushes her away, remaining hard to comfort. Records also note that Infant A is generally cheerful, adaptable, and regular in her routines, while Infant B is intense, irritable, and slow to adapt to new situations. The two children are also being raised in very different home environments. Respond to all three parts: (a)  Classify the attachment pattern of each infant and justify your classification using their reunion behavior. Identify what is considered the hallmark of secure attachment. (b)  Apply Thomas and Chess’s temperament categories to each infant, and use the concept of goodness-of-fit to explain how each child’s long-term adjustment might depend on the home environment. (c)  Connect this situation to Erikson’s stage of trust versus mistrust. Explain how the caregiving each infant receives could shape the resolution of that crisis.

A structural steel wide-flange shape [E = 240 GPa; I = 201 × 106 mm4] is loaded and supported as shown. The beam is supported at B by a 20-mm-diameter solid aluminum [E = 78 GPa] rod. After a concentrated load of 40 kN is applied to the tip of the cantilever, determine the force produced in the aluminum rod. Assume the length between B and C is decreased by a factor of 5π.
