System Dynamics-Time Domain Analysis of Dynamic Systems
mass =8kg stiffness =90N/minitial displacement =0.1m initial velocity =0.9m/s
Assume the system is underdamped, and the damping ratio is 0.5. Find the corresponding damping coefficient c. Identify the system parameters such as the natural frequency and damped frequency. Derive the mathematical expression of the displacement as a function of time with the given initial condition. Plot your result.
For the underdamped system in above question, NO initial conditions are applied. Input force is a unit step function of 1.5 N. Derive the mathematical expression of the displacement as a function of time. Plot your result.
find the natural frequencies of oscillation of the double-pendulum below where m1=m2=m, and L1=L2=L.
Determine the force in member BC. After the truss is sectioned use a single equation of equilibrium for the calculation of each force. State if these member is in tension or compression. Take F1 = 2 kN , F2 = F3 = 3.8kN , F4 = 5 kN, F5 = 3 kN.
Verify that heating the wire may be treated as a lumped-capacity process, find the steady-state temperature of the wire and find how long it takes for the temperature of the wire to reach 100°C.
