A steel cube is being subjected to principal stresses σ1, σ2, and σ3 from x, y, z sides. Under what constraint, according to Tresca, will the cube never fail/yield/break, regardless of how much you increase the value of σ1, σ2, and σ3 ?

A cantilever beam of length L has flexural rigidity EI. It is fixed at the right end and free at the left end. A downward concentrated load P is applied at the free end, and the vertical deflection at the free end is  PL3/(xEI)Using Castigliano’s Second Theorem, what is x? ​

Q2 subpart Rounded to the nearest integers, what are the magnitudes of three principle stresses at the location above?σ1 = [1011]  MPaσ2 = [zero] MPaσ3 = [56] MPa Only enter positive INTEGER numbers, no units, no space. They will be three different numbers and |σ1| > |σ2| > |σ3|.

In a preschool classroom, a teacher notices several things in one afternoon. A 4-year-old, Priya, learns the new word “telescope” after hearing it just once, but she frequently interrupts and struggles to take turns in conversation. While building a block tower alone, she talks aloud to herself, narrating each step. At the play tables, one child stacks blocks to construct a castle, two children sit side by side each playing with their own dolls without interacting, and a group of four runs a pretend “restaurant” together, assigning each other roles. One boy announces that boys are not allowed to use the play kitchen. A parent of an 18-month-old sibling asks the teacher how much screen time is appropriate. Respond to all three parts: (a)  Identify and apply three language concepts from the chapter: fast mapping, private speech, and pragmatics. Tie each to a specific detail in the scenario. (b)  Classify the types of play shown at the three play stations and explain what each type indicates about social or cognitive development. (c)  Explain the boy’s belief about the play kitchen using gender schema theory, and state what the American Academy of Pediatrics recommends about screen time for a child this age, with a brief reason.

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.

Maria and Tomas are first-time parents of a healthy 6-month-old, Lucia. They have noticed that Lucia gained steady control of her head and upper body before she could reach out and grab toys, and that she still cannot crawl. At her checkup, the pediatrician plotted Lucia’s height and weight against growth norms and said she is right around the 50th percentile. The parents are also weighing two pieces of advice: their pediatrician encourages continued breastfeeding through the first year and safe-sleep practices, while Lucia’s grandmother insists formula is just as good and worries that Lucia is “behind” because a same-age cousin already pulls to stand. Respond to all three parts: (a)  Use the cephalocaudal and proximodistal principles to explain the order in which Lucia is gaining motor control. Apply each principle directly to the behaviors described. (b)  Explain what a growth norm and a percentile actually represent, and use that to evaluate the grandmother’s claim that Lucia is “behind.” Why should norms be interpreted with caution? (c)  Give Maria and Tomas two evidence-based recommendations drawn from the chapter, one about reducing the risk of SIDS and one about the benefits of breastfeeding during the first year.
