What is the equation for the natural frequency of a cantilever beam?

If you know the natural frequency and the mass of the load and beam... k=Wn^2*m (where k=stiffness, Wn=natural frequency, m=total mass) If the beam's mass is not negligable then the total mass is... m= m(load)+1/4m(beam) I'm wondering if this link might help you ;-) http://www.vibrationdata.com/StructuralDC.htm Here is a paper that solves a problem by studying the Cantilever Beam. A few pages into this paper, it has the mathmetical expressions for its the first 3 vibration modes and frequencies. http://faculty.uml.edu/pavitabile/22.403/web_downloads/Final_Project_Cantilever_101806.pdf One more link: http://www.kxcad.net/RecurDyn/RecurDyn_Ver6.3/programmanual/Eigenvalue_Analysis/Application/Cantilever_Beam/Cantilever_Beam.htm

What are the uses of cantilever beams in real life?
A cantilever beam is often used for making balconies in residential architecture. A cantilever beam is a beam that is supported only one of its ends while the open end can support a certain weight.
What is the support reaction at prop for a propped cantilever beam subjected to uniformly distributed load?
conclusion reaction and moment for propped cantilever beam
What are the types of beams in an aircraft?
cantilever beam,contineous beam,fixed beam,simply supported beam
What is the max length of RC cantilever beams?
1.50 meter from the support is the max. safe length cantilever beam
What is the difference between a cantilever bridge and a beam bridge?
A Cantilever bridge is built from iron, structural steel and prestressed and reinforced concrete. These materials make the trusses, box girders, vertical columns and the canitlever itself.
Is Natural frequency and Resonance of a Cantilever Beam will be same?
The natural frequency of an undamped beam is the same as the resonant freqency. In the case of damping the Resonant_Frequency = Natrual_Frequency * sqrt( 1 - DampingRatio2)
First three natural frequencies of vibration of a cantilever beam?
3
What is the point of a cantilever beam?
a cantilever beam is designed to evenly distribute weight
Difference between determinate and indeterminate structures?
determinate structures are analysed by using equation of equilibrium or statics ie.., EV=0,EH=O,EM=0. EXAMPLE: simply supported beam ,cantilever beam,single or double over hanging beam. indeterminate beams are not capable of being analysed by using equation of statics. along with equation of statics we need some conditions for finding the unknowns. Example : fixed beam, propped cantilever beam, and continuous beam
What is the Effect of spring stiffness on natural frequency?
the spring stiffness effect the natural frequency of the beam. the increasing value of spring stiffness lead to the increase value of natural frequency of the beam also.
What is the max length of cantilever beam?
1.50 meter from the support is the max. safe length cantilever beam

How do you find natural frequency of wind turbine tower?
Solve by treating tower as a cantilever beam and lumping some of the tower mass at the top. First find the deflection of the tower, from this find the stiffness. The lowest natural frequency is sqrt(k/m), where m is the mass at the top of the tower plus the 0.23mass of the tower that can be lumped at the end.
What is the support reaction at prop for a propped cantilever beam subjected to uniformly distributed load?
conclusion reaction and moment for propped cantilever beam
What are the types of beams in an aircraft?
cantilever beam,contineous beam,fixed beam,simply supported beam
Will a cantilever slab have beam at its free end?
no
What is a deflection in cantilever beam?
it will depend upon the load and moment applied on the beam.
