del = Wl/AE is same for all longitudinal vibrations?

Useful the videos

Sir delta 2 value shown in my Casio is 0.0108 how to convert 0.0108 into 10.86×10 to the power of minus 3 ???

Sir BE length is 1.5, how do we get 0.5

Sir try 2/3 times but i got magnitude 9 and degree 210 😢

Thanks sir

Sir need ans for these two question

A vibrating system having mass 1 kg is suspended by a spring of stiffness 1000 N/m and it is put to harmonic excitation of 10 N. Assuming viscous damping, determine (i) the resonant frequency (ii) the phase angle at resonance (iii) the amplitude at resonance (iv) the frequency corresponding to the peak amplitude and(v) damped frequency. Take C = 40 N-sec/m.

A rotor of mass 10 kg is mounted mid-way on a 20 mm diameter horizontal shaft supported at the ends by two bearings. The bearing span is 800 mm. Because of certain manufacturing defect, the centre of gravity of the disc is 0.1 mm away from the geometric centre of the rotor. If the system rotates at 50 r.p.s., determine the amplitude of steady state vibrations and the dynamic load transmitted to the bearings Take E = 200 GN/m2

Brilliant work sir

Nice explanation sir..

Thank you sir...

Very good explanation and helpful

Hi sir tq you sir it is very helpful in lockdown period so plse upload more University solved problems sir🙏🙏🙏🙏

SUPER Sir

GREAT SIR

Spr sir
