Explain with a sketch, and without calculation, what type of load bar AJ is exposed

Posted on January 16, 2021 by Geoffrey

Figure 1. Trusses Figure 1. shows a truss composed of poles. It is stored in fixed bearing A and fixed bearing B. At the nodes N, P and R, forces act as shown in the figure. All joints are torque and friction free. Explain with a sketch, and without calculation, what type of load bar […]

Consider the following model:y=Xβ+;∼(0,σ2Ω)(10)whereXis ann×knon-singular matrix of regressors that are fixed in repeated sampling,βak×1 vector of unknown parameters,ann×1 vector error term, andΩann×npositive definitematrix.a) LetΩ=InwhereInis an identity matrix of ordern. Letˆβdenote the ordinary least squaresestimator ofβ. Consider any arbitrary linear estimator ̃β∗. Show thatˆβindeed attains theminimum sum of squares of residuals compared to any other ̃β∗.[40%]b) […]

Determine the correlation between return on capitol employed and profit,

Posted on January 5, 2021 by Geoffrey

Here we analyse the extent to which the profit margin for manufacturers in the data set can be predicted using the other quantitative variables in the data set. We use scatter diagrams to determine the correlation between return on capitol employed and profit, and between return on shareholder funds and profit. The R squared value […]

What do unequal impulses tell you about the motion of the participant?

Posted on December 30, 2020 by Geoffrey

Analysis of Running Question: Compare the relative sizes of the braking impulse and propulsive impulse in the slow run and the fast run. Is this what you expect? What do unequal impulses tell you about the motion of the participant? Question: In each activity, what was the velocity of the participant’s centre of mass at […]

Is the energy conserved for the ball? If not, what is the energy transferred to?

Posted on December 28, 2020 by Geoffrey

Energy is transferred from one from to the other. For this part of the lab you will be using a ball and phyphox app on your phone. Open the phyphox app and select (in)elastic collision. Select settings and change the threshold to 0.05 au and minimum delay to 0.1 s. Place the phone on a […]

Was the experiment carried out with appropriate measurements and precision?

Posted on December 14, 2020 by Geoffrey

Are the independent, dependent, and control variables clear and appropriate? Does the experiment actually address the hypothesis? Was the experiment carried out with appropriate measurements and precision? Is a thorough and accurate understanding of the relevant physics demonstrated? Is the experiment original (we didn’t already do it in class and I can’t find it in […]
