Many thanks bro, problem solved! It was due to the mode constant
Scott Whitney's suggestion
Total motion: 325Htot.scm
1st mode: 325h1st.scm
2nd mode: 325h2nd.scm
3rd mode: 325h3rd.scm
4th mode: 325h4th.scm
Book's...
1st frequency for example, hand calculations give 5Hz while generated value shows 15Hz. This is a huge difference, and I need to know why if it is supposed to be different.
2 pie converts rad/s to Hz, not a crucial point in this case.
Hi all,
I am new to the forum and am despreate for the solution for my current task. I am given a canteliver beam with the dimention:
L =1250mm
W= 75mm
D= 30mm
E=200 Gpa
density = 7800kg/m^3
poison ratio=0.3
and I optained the first five natural frequencies from COSMOSWorks 2007...
