Can you become a mechanic by reading books?
Well I am really wondering about thsi right now as I read that I should really try to further my education via Distance learning .

Cyclic volume changes in rubber
This is a study dealing with the volume variation in filled crystallizable natural (F-NR) and uncrystallizable styrene butadiene (F-SBR) rubbers subjected to cyclic loadings. During their deformation, such materials exhibit volume variation induced by the cavitation phenomenon and the decohesion between particles and the rubber matrix.
please help!! two solid mechanics problem relating stress, gears etc.
hi
i am having problems solving two solid mechanics problems... can anyone please help??? the problems are:
Question 4:
A 2380 Nm torque is applied to gear D due to input torque from the motor at A, as shown in figure 4. Shafts 1 and 2 are both solid steel, 44 mm in diameter and 600 mm long. Gear B has a diameter of 250 mm and gear C has a diameter of 350 mm. The shear modulus G for steel is 80GN/m^2
Find out:
(a) the maximum stress in shaft 2
Journal Club Theme of March 2009: Mechanics Issues in Nanocapacitors and Ramifications for Energy Storage
Next generation advances in energy storage for nanoelectronics, micro and nanosensors among others, require capacitors fabricated at the nanoscale. High dielectric constant materials such as ferroelectrics are important candidates for those. Consider the following: the expected capacitance of a 2.7 nm SrTiO3 thin film is 1600 fFmicro-m-2. What is the likely value in reality? 258 fFmicrom-2! This dramatic drop in capacitance is attributed to the so-called "dead layer" effect.
Volume variation in filled and unfilled natural rubber : competition between cavitation and stress-induced crystallization
this is a study on the competition between cavitation and stress-induced crystallization during the deformation of cis-1,4 polyisoprene rubber. During deformation, this kind of material exhibits volume variation induced by both phenomena. In this study, we propose to measure this volume variation by an original full-field measurement technique. The high resolution of this technique allows us to identify characteristic stretch ratios during mechanical cycles.
Parametric modelling help!!!!!!!!!!!!!
Hiya.
I want to run example paramtrized input files on Abaqus. I do this by importing it as a model. However, when i do this, an error message comes up saying:
WARNING: The input file contains one or more data items which have been parameterized. Parameterized input files can not yet be imported into Abaqus/CAE. This occurred while scanning input file for parameterized data. The input file will not be imported.
I really need to overcome this problem. Is there anyone out there that can help?
