I'm working on a project using LAMMPS. I am very new to the software and find the documentation doesn't always answer the fundamental questions I have. I noted previous LAMMPS queries were posted on this forum, although I am from a mechanical/materials engineering background.
I am trying...
I am currently undertaking a module in Failure Analysis, one topic of which is vibration monitoring of bearings.
During this study, the notion of first and second Kerr diagrams as a tool for analysis came up. I have been trying to find additional information on Kerr diagrams; however, outwith...
Determine the closed loop transfer functions of the systems shown below:
Standard block diagram algebra.
The Attempt at a Solution
I've moved the take off point such that the diagram now looks like:
I am having difficulty determining G1(s). The...
I'm currently working on a problem involving the calculation of an unknown voltage source of a circuit containing a resistor, inductor and load in series.
Unfortunately, the problem sheet does not give an answer at the end, so I am unsure as to whether my approach is correct -- hence...
I'm an undergraduate engineer currently studying mechanical engineering. The first two years of my degree are core for all mechanical engineering students; however, at the end of second year, I have the option of taking a specialism in electrical engineering, offshore engineering, or...
A tyre pressure gauge indicates 20 N/cm2 for a tire at 34°C after a fast motorway run. Assuming that the volume of the air in the tyre is constant, atmospheric pressure is 760 mmHg and the air gas constant is 0.287 kJ/kg.K:
i) Estimate the indicated pressure when the tyre...
A colliery lift cage can be considered as a simple hoist system. An investigation found that when raised from the bottom of the mineshaft, the cage accelerates uniformly for 10 seconds, travels for 70 seconds at constant speed of 3 m/s and just before reaching the pit head...
I have an basic kinematics problem I can't seem to grasp -- hopefully someone can shed some light on it for me?
The acceleration, a, of an object is equal to a=s, where s is the
distance from the start position. Sketch a graph representing velocity
against distance, s, for the...
