hello every one
is it possible to make a cantilever whose natural frequnecy is less than 1Hz.
if yes what will be its dimensions if the youngs moduless is taken as 2200 n/mm^2 ?
what will be the minimum resonent frequency that i can reached with?

Can anyone give a definition about strain energy density for a plate? When a plate under a uniform stretch s, some gives an equation like ek=Es2/2(1+μ)(1-2μ), some gives ek=Es2/2. What are the difference of these two definition? Please note both of the cases are for plane stress conditions. If under plane strain conditions, what is the definition for its strain energy density? Thanks for help.
