Single degree of freedom vibration problems with forcing functionsNeed help with this Undergraduate problem where two dampers are in series.
For a vertical spring/damper system with mass (M) and a harmonic forcing function, Fmax Cos [omega x t] , two dampers are in series with coefficients, C1 and C2, and a single spring with constant, k.
Determine the amplitude of the steady-state displacement.
Determine the critical damping coefficient, Ccr.
The maximum flow past a circular cylinder is 2 X the Up stream velocity. The max velocity occurs at the center line of the top of the cylinder.
Komodo dragons are the largest lizards known to man. A 250-pound dragon can eat enough food to increase it body weight by 1/2. Which number sentence could be used to find w, the weight of a k0modo dragon after increasing it body weight by 1/2?
Steam enters a turbine operating at steady-state at 700 ºF and 600 lbf/in2 and leaves at 0.6 lbf/in2 with a quality of 90%. The turbine develops 12,000 hp
A piston-cylinder device contains 0.8kg of steam at 300 degrees C and 1 MPa. Steam is cooled at constant pressure until one-half of the mass condenses.
Determine maximum total bending moment (static plus dynamic) of the beam under steady-state conditions.
write a reflective assessment of how you rate yourself against these competencies and Describe the main learning outcomes that this course and the EWB project have generated for you over the semester. Have any of these learning outcomes been a ..
Calculate the head provided by the pump and Calculate the brake power required if the pump efficiency is 75% (kW).
SEM212 - Aim of this demonstration is to use measurements of the load required to propagate a crack (tear) in packaging tape to determine its fracture toughness.
Cantilever Beam with maximum tensile strength. A cantilever beam is to be made using a symmetrical I section beam. The cantilever is to carry a load of 40kN at a distance 2.5m from the fixed end. The situation allows for a depth of I beam to be no..
Determine Fourier Number, Compare two identical steel spheres, except the first has a two inch diameter while the second sphere has a four inch diameter. The larger sphere will have a Fourier number approximately
In the idealized model attached shown, m = 15 kg, k = 135 N/m, and the viscous damping ratio is 0.15. Assume that an external harmonic force F(t) = 15 cos 4 t acts on the system with F0=15 N and forcing frequency of 4 rad/s.
Determine the largest allowable square cross section of a steel shaft of length 6 m if the maximum shearing stress is not to exceed 135 MPa
