A wаll fооting hаs the fоllowing conditions. Determine the criticаl one-way shear, Vu, at a distance of d from the face of the wall. Assume the footing is 4 ft wide, the pressure that acts on the bottom of the footing is 5,900 psf, and the reinforcement is a #6 bar spaced every 12 inches.The bottom of the footing is at a depth of 4 ft below grade.The service dead load is 9 kips/ft, and the service live load is 8 kips/ft.The wall is 16 in. thick.The footing is 10 in. thick.The allowable soil pressure, qa, is 5,000 psf.The soil has a density of 120 lb/ft3.The concrete has a density of 150 lb/ft3.The concrete cover has a thickness of 3 in.f'c = 3,500 psi and fy = 60,000 psi.

Imаgine yоu аre interested in аssessing whether jоb satisfactiоn differs among employees in a manufacturing setting based on the type of technology they use—automated machinery versus manual tools. Additionally, you want to explore if there are variations in satisfaction based on the employees' daily technology use (high versus low). You set up a study with 30 workers who are high daily users of technology and 30 who are low daily users. Each worker participates in two sessions: in the first session, they operate manual tools while doing a manufacturing task that they have never done before, and in the second, they work with automated machinery to do the same manufacturing task. a. [4 pts] What is/are the independent variable(s) and dependent variable(s)? List all of the levels of the independent variable(s). b. [4 pts] Provide one operationalization/measure for the dependent variable with good construct validity. State what scale of measurement your chosen operationalization belongs to. c. [2 pts] Is this a between-subjects, within-subjects, or mixed factorial design? Explain why using the independent variables. d. [10 pts] Define construct validity and internal validity. For each concept describe how poor construct validity and internal validity may impact the results of this study. Construction Validity: Internal Validity:
