Mode Conversion Material Properties: Material strain is proportional to material stress. Elastic Modulus : The ratio of the stress applied to a body to the strain produced. Mode Conversion When sound travels in a solid material, one form of wave energy can be transformed into another form. For example, when a longitudinal waves hits an interface at an angle, some of the energy can cause particle movement in the transverse direction to start a shear (transverse) wave. Mode conversion occurs when a wave encounters an interface between materials of different acoustic impedances and the incident angle is not normal to the interface. In the previous section, it was pointed out that when sound waves pass through an interface between materials having different acoustic velocities, refraction takes place at the interface. Snell's Law holds true for shear waves as well as longitudinal waves and can be written as follows. Where: VL1 is the longitudinal wave velocity in material 1.
The Top 6 Popular Free Email Providers Online Other Than Gmail & Yahoo Personally, I am happy to give my entire online existence over to Google. They have my email, my Analytics data, my search history, my mobile device, my credit card information, and the list goes on.

Those same people may still want to reap the benefits of web mail (in contrast to plain old desktop email, powered by Thunderbird and its ilk). So I’ve gathered up a list of several popular free email providers that you might want to take for a spin if Gmail or Yahoo are not your thing. Outlook.com Microsoft’s webmail offering underwent a somewhat similar cycle to its Web browser: Like Internet Explorer, Hotmail used to be a dominant force in webmail.

Even if you’re perfectly happy with your current webmail provider, Outlook.com is well worth a look. Mail.com Yandex Mail Hushmail Zoho Mail Final Thought

7 Surprising Kick-Ass Things You Can Do with Google Sketchup As a part of Google's quest to be the undisputed overlords of the Internet, they've made a lot of quality services available for free. Gmail, Google maps and Google Docs are all famous examples, but one of the search giant's coolest free offerings, Sketchup, flies under a lot of peoples' radars. Sketchup is a free 3D modelling tool developed based on the philosophy that by giving people a small set of powerful, intuitive tools, you can lower the barrier of entry to 3D modelling, so that almost anyone can make quality 3D models with just a couple of sessions of practice. Still not conviced to give Sketchup a try? There’s something oddly rewarding about seeing a tiny version of your house. 1) Obtain a floorplan of the building. 2) Make a 2D replica of the floorplan in Sketchup. 3) Finally, use the “Push/Pull” tool to extrude the walls you’ve drawn up. And that’s it! If you’d like more in-depth instructions about how to do this, Google has an excellent video tutorial here.
