Pipe (2) is supported by a pin at bracket C and by tie rod (1). The structure supports a load P at pin B. Tie rod (1) has a diameter of 10 mm and an allowable normal stress of 110 MPa. Pipe (2) has an outside diameter of 54 mm, a wall thickness of 6 mm, and an allowable normal stress of 165 MPa. Assume x₁ = 3.6 m, x₂ = 1.2 m, and y₁ = 3.5 m. Determine the maximum load P_max that can be supported by the structure without exceeding either allowable normal stress.

Select one:

True

Chinese consumers are increasingly being influenced by video bloggers, columnists, and photobloggers on social media platforms including Instagram, WeChat and Weibo. Becky Li, with more than 7.5 million combined followers on WeChat and Weibo, is one of China’s top fashion bloggers in China. She is regarded as one of China’s influencers in the fashion world and offers good content of shopping and experience advice.

b) Give TWO reasons why the source of social influence identified in (a) can bring influences on consumers. Illustrate EACH reason with ONE supporting reference from the case.

c) Name the source of social influence used in the above case of which “consumers form a structured set of relationships involving a particular brand online – for Zhang Dayi’s online brand”. Discuss the characteristics of your identified source of social influence.

Describe the alignment between the three different types of business strategies and its association with HRM strategies and functions. What business strategy has Xiaomi adopted and how would this strategy impact their SHRM approach? Question 2 Given that Xiaomi has grown its international operations significantly in the last 7 years, the company has had to adopt an aggressive recruitment and training strategy. Based on the systems approach to HRD, the first step of the process is to conduct a HRD needs analysis. Describe how Xiaomi would conduct a HRD needs analysis. Question 3 How would Xiaomi then evaluate the effectiveness of the HRD programs?
