How to solve a symbolic equation for vibration system

Hi, friends.

Is there a way to solve the symbolic solution for a vibration system in mathcad?

Such as f(t)=0, and the solution should be in the form of Asin(wt+a)+Bcos(wt+a)

Thank you in advance!

Looking forward to your help!

Shawn

Ah, you wanted the general, symbolic solution. Well here goes:

Success!

Mathcad cannot solve differential equations symbolically.

Hi, Richard,

What if I define the values for these parameters?

say:

m=10, mb=5, E=29000, I=500, L=15.

Is it possible to find the function of v(t)?

Thank you

Not using the symbolic processor, no. I don't know if it can be solved using Laplace transforms, it's not something I have any experience with. LucMeekes seems to be kind of a whiz at that though, so maybe he can give an opinion (or, even better, a solution!)
