A full derivation of the 2 nd four bar linkage can be found in R.L.NORTON. Working model is a 2D analysis software package that allows linkages to be. Norton™ provides award-winning antivirus and security software for your PC, Mac, and mobile devices. Now includes LifeLock Identity Theft Protection. Norton protects your devices against viruses, ransomware, malware and other online threats.

How antivirus software works Antivirus software looks at the data—web pages, files, software, applications—traveling over the network to your devices. It searches for known threats and red-flags behavior to block or remove malware as quickly as possible. What is malware? Malware (short for malicious software) is a program specifically engineered to compromise the security features on your computer or mobile device to give cybercriminals access to your personal data and, in some cases, commit identify theft. Malware sneaks in through a hole in one of your software programs, hidden in an online ad or disguised as a legitimate app you download. Most of the time, the presence of malware will be obvious even though you might not know how it got on your device.

In fact, most people have no idea that malware has been installed until their computers start acting funny. Computer security almost always begins with anti-virus/malware software. While this advice may be obvious to some, many home computers don’t have proper security software installed. Make this a priority on your home computer; it’s the best thing you can to do to avoid malware.

With public Wi-Fi available everywhere, what seems like a convenience can actually put you at risk. Free public Wi-Fi is a hacker’s playground for stealing personal information. One of the dangers of using a public Wi-Fi network is that data over this type of open connection is often unencrypted and unsecured, leaving you vulnerable to a man-in-the-middle (MITM) attack. Another risk of using free public Wi-Fi is that you may be connecting via a rogue hotspot. Once a victim connects to the rogue Wi-Fi hotspot, the host hacker can then intercept data and even use tools to inject malware into the connected devices. 2 Virus Protection Promise: To be eligible for the Virus Protection Promise, you must have a qualifying Norton subscription and unless you have Norton Small Business, you must also have purchased, renewed or upgraded that Norton subscription directly from Symantec, or activate automatic renewal with Symantec.

If a Norton expert is unable to remove the virus from your device, then you may receive a refund based on the actual price paid for the current term of your qualifying Norton subscription. If you purchase a Norton bundle (a qualifying Norton subscription purchased with another Norton offering), your refund will be limited to the Manufacturer’s Suggested Retail Price (MSRP) of your qualifying Norton subscription for the current term, not to exceed the total bundled price paid. Or, if your bundled purchase contains a qualifying Norton subscription with a non-Norton product, your refund will be limited to the Manufacturer’s Suggested Retail Price (MSRP) of only your Norton qualifying subscription for the current term, not to exceed the total bundled price paid.

Any refund will be net of any discounts or refunds received and less any shipping, handling and applicable taxes, except in certain states and countries where shipping, handling and taxes are refundable. The refund does not apply to any damages incurred as a result of viruses. See for details including qualifying Norton subscriptions.

You have been given the assignment to evaluate a software package for you company. You want to be able to evaluate position, velocity, and acceleration analyses which are important for the design of your linkages. (In this lab you will learn to use the software that accompanies the Norton text for doing velocity and acceleration analyses of a four-bar linkage. Appendix A in your text is a user's guide that gives detailed information on how to use the software.) Then you will write Matlab code to serve the same purpose as the commercial code. You will then make a recommendation on purchasing the commercial code vs.

Writing your own. Run fourbar From the main menu go to 'Examples' Create the Chebyshevsky linkage. Select the defaults for calculating the linkage. Animate the linkage. Print the coupler curve (printing procedure is given later in this lab handout) Plot the angular velocity of the coupler vs.

Time Repeat the plot for the output (link 4) Plot the velocity and acceleration for the coupler vs time (2 separate plots). What are the maximums (absolute value)? Create a 4 bar linkage of your own with a coupler point set off the link axis. You cannot use the default linkages in the program!

Select link lengths so that the linkage is Grashoff and repeat steps 5 through 9 for your linkage. Change one link length so that your linkage is non-Grashoff. Repeat steps 5-7 Write Matlab code to determine the position, velocity and acceleration for each link in a 4- bar linkage and for any point on link 3.
