A harmonic force of maximum value 25 N and frequency of 180 cycles>min acts on a machine of 25 kg mass.
Design a support system for the machine (i.e., choose c, k) so that only 10% of the force applied to the machine is transmitted to the base supporting the machine.
steam enters the turbine in a vapor power plant at 1600 psia and 1000f state 1 and expands to a pressure of 1 psia
Your engineering firm decides to build a prototype, and needs screw and nut fasteners as well as resistors and LEDs. There are machinists and electronics technicians available for in-house production. What is the most cost-effective way of acquiri..
You have a large pin made from aluminum with a diameter of 0.01 m. This pin is needed to hold something from the ceiling. You install the pin into a hole of diameter 0.01 m in a piece of tungsten; assume a "perfect press fit". It was very hot, 323K, ..
1 youngs modulus for aisisae 1045 steel is 29.0 x 10 6 psi and its poissons ratio is 0.32. what are its shear and bulk
steam is compressed by a compressor from 120oc and 150 kpa to 200oc and 1.5 mpa. the work input is measured to be 485.4
Calculate the natural frequencies and mode shapes of a shaft in torsion of shear modulus G, length l, polar inertia J, and density ρ that is free at x = 0 and connected to a disk of inertia J0 at x = l.
A 1/10 scale model is to be constructed to verify the performance targets of the prototype turbine and to determine its cavitation limits. The head of water available for the model tests is 5.0 m. When tested under dynamically similar conditions a..
If have to do a material selection case study for a rice cooker outer body where can I find the necessary requirement specifications of the material?
Determine the positions of static equilibrium and investigate the stability of the system at each position. Take the springs to be sufficiently long so that they remain effectively horizontal.
saturated stream at 100 lbin2 abs is used to heat co2 in a cross flow heat exchange consisting of 4 14 in od brass
Water is being pumped from a large lake to a reservoir 30 m above at a rate of 5x10-3 m3/s by a 12 kW (shaft) pump. If the irreversible head loss of the piping system is 8m, determine the mechanical efficiency of the pump.
If the filling is done rapidly, calculate the final temperature in the small cylinder, (a) assume that oxygen is an ideal gas with Cv= 5R/2 and (b) using accurate thermodynamic data for oxygen.
