Q1. The figure shown below is extracted from bending stress in a beam experiment where an inverted Aluminum (E 69 GPa) T-section is subjected to two point-Loads (each 1/2W). The strain across the depth of the cross section is measured using strain gauges which are sensors that experience a change in electrical resistance when stretched or compressed. Connections to digital strain display Beam Loading frame Pin support -Retaining pin Strain gauges Locating hole for STRBA load cel...

I need guidance
here is the graph that I just created for #2
FI= \kAl 1. Where k is the spring constant and Al is the change in the length of the spring. This relationship is called Hooke's Law. In your class vou will discuss this in more detail and include direction, and any appropriate offset or discussion of relaxed or equilibrium position. we find the spring constant by applying a force and measuring how far the spring stretches from...

Two researchers conducted a study in which two groups of students were asked to answer 42 trivia questions from a board game. The students in group 1 were asked to spend 5 minutes thinking about what it would mean to be a professor, while the students in group 2 were asked to think about soccer hooligans. These pretest thoughts are a form of priming. The 200 students in group 1 had a mean score of 25.5 with a standard deviation...
