Thanks a lot for you reply...however i think you have misunderstood the concept here. You are referring to joints while i am referring to DOF's. I can see what you mean but i think you are wrong but no worries There are 6DOF's in this structure...2 horizontal and 4 rotational...shown on the...

Hello, i didnt really understand what you mean by that.

If anyone thinks that i am missing any useful information please let me know

Homework Statement Hello everyone, as you can see from the picture below this is a 2 storey frame with 6DOF's (2 translational DOF's = u1 and u2, 4 rotational DOF's = u3, u4, u5 and u6). i would like to determine the consistent mass matrix (6x6 and symmetric) of the frame without carrying...

From the manual the only way to do what i am looking for is to use the table function where you need to input a the range of your values with a given step however this is not what i am looking for. I would like to input values for t that are not necessary in order or with a given step between a...

anyone? i know that is possible could you please help me?

Hello everyone, I was just going through the manual of my casio fx-350ES calculator to find out how i can input an equation with one variable. let's say the equation below: (t/5)^1.514 t being the variable Then i would like to input a range of values for my variable, t so that i can...

ok thanks alot

Hi, i did not got back to my post for a while because we managed to solve this and found all four values for λ by using iteration in excel. However the determinant was not exactly zero with the results we got but we were allowed to use them. Moreover i was interested to see how a 4x4 matrix is...

Hey thanks a lot for your reply. I think i will try to solve this by hand and then solve the quartic polynomial in wolframalpha as you suggested, however since i have not tried to solve a 4x4 matrix before i will post a picture of an example of how i think this can be solved so that you can let...

Homework Statement As you can see from the picture below this a 4x4 matrix with an unknown value, λ. My objective here is to find four values for λ so that the determinant of the 4x4 matrix is equal to zero. http://i49.tinypic.com/n4cenn.png Homework Equations The above 4x4 matrix is the...

Ok thanks a lot for you reply

How to make γ the subject of the formula? (logarithms involved) Homework Statement My problem here is that i want to make γ the subject of the formula so that i can calculate it since all other variables are know. As you can see from the equation below there are two γ inside the equation one...

I am looking for a formula to find the maximum bending moment for a trapezoidal loading, can anyone point me out to it?

yes the beam is fixed at both ends...i am designing the beam, actually i am designing a whole steel frame structure with the aid of a professional software called SAP2000 and the joints need to be fixed because i am not using any vertical bracing. I have already developed a shear force diagram...
