A slider-crank linkage has r = 3 and l = 12. It has an angular velocity of 200 rad/sec at time t = 0. Its initial crank angle is zero. Calculate the piston acceleration at t = 1 sec. Use two methods, the exact solution, and the approximate Fourier series solution and compare the results.
For the roller coaster seat described in Prob. 4.92, determine a wrench equivalent force system and specify the x and z coordinates of the point where the wrench's line of action intersects the xz plane.
The deepest known point in the ocean is 11,034 m in the Mariana Trench in the Pacific. Assuming sea water to have a constant density of 1050 kg/m3, determine the pressure at this point in atmospheres.
In each cycle, the change in internal energy of the refrigerant when it leaves the compresser is 1.2×105 . What is the work done by the motor of the compressor?
Let H/ z ) be the system function of a discrete-time prototype low-pass filter. Consider a new discrete-time low-pass filter whose system function H( z ) is obtained by replacing z in H/ z ) with ( z - a )/{1 -az ), where a is real.
An insulated tank is divided into two parts by a partition. One part of the tank contains 2.5 kg of compressed liquid water at 60°C and 600 kPa while the other part is evacuated.
