Numerically integrate and plot the response of an underdamped system determined by m = 150 kg and k = 4000 N/m, subject to the initial conditions of x0 = 0.01 m and v0 = 0.1 m/s, and the applied force F(t) = 15 cos 10t, for various values of the damping coefficient.
Use this "program" to determine a value of damping that causes the transient term to die out within 3 seconds. Try to find the smallest such value of damping remembering that added damping is usually expensive.
The placement x of the applied 100-kN load so that the beam remains horizontal.
Saturated water vapor is contained in a rigid container. Heat is then added until the pressure and temperature become 812.075 MPa and 400 C, respectively. What was the initial temperature of the steam?
two rigid tanks are connected by a valve. tank a contains 0.2 m3 of water at 400 kpa and 80 percent quality. tank b
the tank of water in the figure below is given a constant acceleration ax. if the water is not to spill out of the tank
A pure copper sphere of radius 1 cm is dropped into an agitated oil bath that has a uniform temperature of 130C. The initial temperature of copper sphere is 20C.
Determine the gain error if the circuit is to provide a nominal gain of (a) 5, or (b) 50.
The elevation of the surface of the lake is 928.75, and the invert of the orifice is 905.25. When the orifice is opened, what discharge in cfs flows through into the stream below the dam?
Three kg of gas in a piston–cylinder assembly undergo a process during which the relationship between pressure and specific volume is py 0.5 5 constant. The process begins with p 1 5 250 kPa and V 1 5 1.5 m 3 and ends with p 2 5 100 kPa. Determine th..
A pipe transports water in a 4-cm-diameter pipe with an average velocity of 10 m/s. The pipe undergoes a 90 degree bend and exits out a 2-cm-diameter nozzle. Assuming no friction losses in the bend, the total force of teh water on the bend is nearest..
