THE MOMENTS OF A RANDOM VARIABLE Definition: Let X be a rv with the range space Rx and let c be any known constant. Then the kth moment of X about the constant c is defined as Mk (X) = E[ (X c)k ]. (12) In the field of statistics only 2 values of c are of interest: c = 0 and c = . Moments about c = 0 are called origin moments and are denoted by k‚ i.e.‚ k = E(Xk )‚ where c = 0 has been inserted into equation (12). Moments about the

Objective The objective of this experiment is to compare the theoretical internal moment with the measured bending moment for a beam under various loads. Introduction and Background Theory Definition of a Beam Members that are slender and support loadings that are applied perpendicular to their longitudinal axis are called beams. Beams are important structural and mechanical elements in engineering. Beams are in general‚ long straight bars having a constant cross-sectional area‚ often classified

Bending in beams Key Points: 1. Internal bending moment causes beam to deform. 2. For this case‚ top fibers in compression‚ bottom in tension. Bending in beams Key Points: 1. Neutral surface – no change in length. 2. Neutral Axis – Line of intersection of neutral surface with the transverse section. 3. All cross-sections remain plane and perpendicular to longitudinal axis. Bending in beams Key Points: 1. Bending moment causes beam to deform. 2. X = longitudinal axis

Defining Moments in Canadian History During the 20th century‚ there were many events and situations that helped define the country of Canada. There were positive moments‚ but also a good amount of negative ones. Of course‚ the successful events kept Canadians in a positive light‚ but the negative situations helped Canada learn from its mistakes and went to prove how strong and brave its citizens were/are. The three most defining moments would have to be the Dieppe Raid

I was never that close with her‚ I didn’t visit every week. The reason I had my coming of age moment was not only because she died‚ but because of my mom. “Did you have a good day at school?” my mom asked joyfully. “Yes‚ but it was school‚” I responded sarcastically. I could tell that my mom had a marvelous day at work because she was in a joyous

Instead I just laid in my bed beyond the alarm. This was the first time I’d done so in 24 years. My attitude only deteriorated from there. The sound of my alarm clock every morning reminded me of the destroyed morning regime I’d held for so long. My new routine now added hurling my small alarm clock as far across the my

We traveled along the road for a long time‚ but we passed by a clearing to our right‚ and we saw the greatest set of dirt jumps that we had ever viewed. Though it was getting late‚ a good biker never turns away from such an opportunity. So we checked the extremely high‚ almost vertical dirt mounds. All of them were practically impossible for us at our current shape and ability of biking. Except for one of the jumps that seemed absolutely possible‚ at the time. Ryan and I were really tired so we
