Homework Statement I am designing a fixture to hold a large piece of sheet metal on which a track robot will be tested vertically. Below is a sketch (the sheet metal on which the track and robot will be mounted will be attached to the vertical aluminum extrusions in the back) The weight of the...

The 2m is just the distance to the midpoint, half of the 4m. My main question is am I going about finding the answer to the question in the correct manner or is there some other method I should be using? Thanks

Mt is the moment about the center point of the 5lb tool on the right end. As far as dimensions, they are the same, although I suppose with the way I broke the diagrams into sections it may not look like they correlate very well. The mount point distance of 10 inches in my diagrams isn't in the...

Sorry, I labelled the forces but didn't actually show the spring:doh:. The middle force in the second FBD and the far right force in the last FBD are both the x and y components of the forces on the spring. The top left forces on the third FBD is the first mount point of the spring. Even if the...

I went section by section to try and figure it out, and ended up with the resultant force of the spring being about 44 lb. Not sure where I'm going wrong.

The moment was taken on the lower bar about the midpoint of the tool. It doesn't matter where I position the spring, I simply chose 10 at random just to see if I was finding the force correctly.

Homework Statement I am given a tool that needs to be balanced in the horizontal position with a spring of my design. I need to know the force that the spring will need to exert in order to do this. I am also choosing the mount point, which will be at 10 in. Homework Equations Fsy =...

Homework Statement A flat part with constant thickness b is loaded in tension as shown. The height changes from 50 to 87 mm with a radius r = 4.0 mm. Find how much lower a load can be transmitted through the bar if the height increases from 50 to 100 mm and the radius increases from 4.0 to 10...

Homework Statement Homework Equations δ = Pl/AE σ = P/A The Attempt at a Solution I had calculated the deformation for both the steel and aluminum, and added them together to give me δ = 0.481 mm, which is incorrect. I also thought I could simply plug in the force P = 200kN and the...

Thanks for the response, c1 is the concentration c1(sat) is the saturated concentration. It is supposed to be V*c1.

Homework Statement I am working on a mass transfer problem and have this equation: d/dt(Vc1) = Ak[c1(sat) - c1]Homework Equations Initial conditions: x=0, c1=0 The Attempt at a Solution I know that the result from integration should be: c1/c1(sat) = 1 – e-(kA/V)t But I don't understand...

Thanks for the responses! How would I convert to matrices?

I am trying to plot the magnitude of velocity and position against time but keep running into issues. The error I am getting here is: Subscript indices must either be real positive integers or logicals. Error in project2 (line 46) position(t) = w(1:3);Here is the relevant portion of my...

Homework Statement Given: Initial orbital elements of a satellite a=6652.555663km; e=0.075; i=28.5 degrees; Ω=40 degrees; w=30 degrees; n=0 degrees;Tasks(using MATLAB): 1. Convert orbital elements to position and velocity vectors 2. Use these vectors to initialize the Runge-Kutta...

Homework Statement I am supposed to find the roots of the equation: 10esinx = x2 - 5x +4 in MATLAB using Newton's method with a tolerance of 10-8. There should be three roots. Homework Equations p=po - f(po)/f'(po) |p - po| < TOL The Attempt at a Solution Here is what I have for the code...
