Question

the question is :

And this is solution :

1) why you didn't consider the mass ??

2) why you didn't divide F by 2 in the right hand side ??

A uniform beam AB with mass m 6 kg is hinged at point A and free at point B. It is supported via springs and damper as shown in the figure below. It is also subjected to a harmonic force at its free end. At time t 0, it is pulled down by small displacement 0 0.12 (rad) 1) Derive the mathematical model 2) Find the natural frequency of the system 3) Find the transfer function G F(s) 4) Find 0(t) and plot the response 0() with time (You may use MATLAB) b- 50 N .Sl m F 5 sin(20t) 0.25 m 6 kg m 0.5 m L 1 m

Explanation / Answer

It is a rotational moment then we take moment of inertia instead of mass

It is F/2 not F
