A (really) small problem

Here's a quick one.

Refer to the accompanying figure.

Figure to accompany a really small problem

 

It shows a frictionless glass tube lying on a horizontal desktop. The tube is smoothly bent at a couple of places as shown in the figure.

Suppose that a small steel ball (say, one taken from a ball-bearing) enters the tube at the point A, with an initial velocity of v.

Post-doctoral postion in Mechanical Engineering at NUS

I have an opening for a post-doctoral position starting early next year (Jan 2009) in the broad area of multi-scale mechanics of nano-crystalline (nc) materials. The focus will be on microstructure mediated failure processes in nc materials primarily using continuum mechanics based approaches, but informed by materials science.

If you are interested, please send me (shailendra[at]nus[dot]edu[dot]sg) your CV and the names of at least two references.

Thanks,

~Shailendra

Seeking Summer Internship Opportunity

I am a third year undergraduate student of IIT Kharagpur (www.iitkgp.ernet.in). In the coming summer, we are supposed to do summer training in some industry in, or out of India, whereas if we want to do internship in a university it must be a foreign university (internship in Indian universities is not allowed).

Finance and Mechanics

 

Recent events about the financial crisis and generally spread turmoils on Economics and Financial Environments  lead me to these conclusions.

Critical Speed:  informations, a key issue on finance, reached a critical speed. Maybe this is the "first" critical speed of the system. Speed of informations has reached the same order of magnitude of people's judgement (executives and investors more than others) so there's a sort of over-reaction about actual events.

The 2009 ASCE-ASME-SES Joint Conference on Mechanics and Materials, June 24-27, 2009, Blacksburg, VA

ASCE, ASME and SES will hold their Joint Conference on Mechanics and Materials on June 24-27, 2009 in Blacksburg, VA.  The conference will be chaired by Dr. Ishwar K. Puri, Department Head, Engineering Science and Mechanics, Virginia Tech. The conference web site provides details, including an invitation to submit symposium and organized session proposals, key dates, instructions for the submission of abstracts and registration information.

In short:

A lack of heroes, a lack of open culture

One of the things that I've thought about often in relation to mechanics is:

An Introduction Course on Mechanics

 

We are currently offerring an introductory course on mechanics for junior students for all fields and subjects.  It is a so called general knowledge course for students to know more on certain subjects and fields before a decision on choice of a major is made.  Since the Mechanics Department in our University has not been popular for so long, we have decided to evangalize our field with more glorious history of Mechanics: Newton, Bernoulli, Euler, Clausius, Faraday, and Einstein.

Some write-ups in mechanics

My googling today brought me to this treasure trove of write-ups in mechanics:

This site contains informal (usually rough draft) technical notes and tutorials on topics in mechanics. The sophistication is at the first or second year graduate level. These write-ups include:

New graduate mechanics course at MIT: Mechanics of Heterogeneous Materials

16.223 Mechanics of Heterogeneous Materials

Course Description: Mechanical behavior of heterogeneous materials such as thin-film microelectromechanical systems (MEMS) materials and advanced filamentary composites, with particular emphasis on laminated structural configurations. Anisotropic and crystallographic elasticity formulations. Structure, properties and mechanics of constituents such as films, substrates, active materials, fibers, and matrices including nano- and micro-scale constituents. Effective properties from constituent properties. Classical laminated plate theory for modeling structural behavior including extrinsic and intrinsic strains and stresses such as environmental effects. Introduction to buckling of plates and nonlinear (deformations) plate theory. Other issues in modeling heterogeneous materials such as fracture/failure of laminated structures.
