    Undergrad Confidence interval/statistic question

    The more I read on the internet, the more I think this problem requires the use of Weibull plot.

    Undergrad Confidence interval/statistic question

    Hi all, I am trying to do something that I am not sure how exactly it can be done. Not very good at statistics. I have a bracket, sample size of 26, that was designed for 120lbs. It holds weight from 120lbs to 150lbs. Only 1 amount of weight gets applied at a time. Each of the bracket...

    Weight supported by two supports

    Hi all, I am working on a problem that I can't even seem to figure out where to start. I have a horizontal beam of known weight (1100lbs, or 4893N). It is 1714.5mm long, and is supported by two vertical supports, which are at known location along the beam (Support 1 @ 200mm; support 2 @...

    Volumetric flow rate of air into a tank - Fluid Mechanics

    Thank you! So yeah, it is a closed cylindrical tank with one port sucking the fluid in the tank, and other port with a vent exposed to the open air. The purpose of the port is to avoid vacuum inside the tank. EDIT: How come it doesn't take into account the diameter of the vent hole? Pretty...

    Volumetric flow rate of air into a tank - Fluid Mechanics

    Hi all, I am stuck on a problem, and it's been a while since I took fluid dynamics. I have a cylindrical tank of know capacity with an inlet, where a vent is attached, and an outlet, the fluid gets sucked. The tank has fluid in there with known volume and density. If I know the usage rate of...

    Temp to raise fluid temp inside a container - Heat transfer & thermodynamics

    Any ideas? Any help or direction will be appreciated. UPDATE: In addition to the information above, I can figure out the mass of the gasoline from the volume and density, and use q=m*cp*(T2-T1), and this will give me heat in Joules, but I don't know how to take into account the temperature...

    Mathematica Plotting equation in mathematica? Any Ideas?

    Hi, I am trying to graph (x+(1/√(1+cos(x)²))) in mathematica, and i used Plot[x + (1/(sqrt (1 + cos (x)^2))), {x, 0, 9}] but I am not getting an output graph. Any ideas?! Plot[x + 1/Sqrt[1 + Cos x^2], {x, 0, 9}, PlotRange -> {-10, 10}] I found few errors, and above is what I got, it's a...
