problem 1:

Illustrate the procedure of finding natural frequency of the vibrations by Dunker leys method with help of simple supported beam acted by three point loads at equidistance along the span.

problem 2:

Illustrate the equivalent stiffness concept. Find out the equivalent stiffness of the beam cable system, if the mass is 800 kg. Also find out the frequency of oscillations as shown in below figure 1.

problem 3:

For the three nodded cantilever beam as shown in figure 2, find out global stiffness matrix and lumped mass matrix.

problem 4:

prepare down the wave equation for longitudinal vibration of tapered bar and when subjected to external forces and offer the displacement boundary situations for all end situations.

problem 5:

A ramp-step forcing function described in figure 3 acts on a spring-mass system. Acquire the shock of this forcing function.
