Write 2 pages analysis about the linkages that MUST match these requirements.

• These pics shows our design HOWEVER, we need to change it to what is written down.

• Need a crank-slider system where the slider can reach at least 50mph and has a long enough stroke that we can load another puck between revolutions.
• keep in mind that dimensions should be easily scaleable.
• Make parts that can be scaled down to under 8 inches.
• The motor is going to hook directly to the linkage, then gear it down to run the cam for the loader.
• I want to aim for a 1/4 scale model, so no parts over 32 inches. We can only print 8in parts.
• Must use Norton Software Linkage
• what is the angular speed of the crank you are using in you calculations?
• Must include MATLAB Codes and references.
• The MATLAB codes below should work for some of the analysis

Sample Solution

Trump’s power is fueled by the whiteness agenda. Other factions believe that the despite the forward strides in American politics such as, the role of Martin Luther King Jr. and having a black president, agreeing that Trump is potent is to deny the steps made forward. The idea of acceptance of the issues of racism in the current politics of the US frustrates the leftists who would rather have other discussions. Interestingly, while the blacks suffer lifelong bondage, the whites who had been united by slavery also suffer the temporary bondage of indenture. History reminds Americans that slavery was such a divisive issue that determined the whiteness today.
Slavery gave birth to racism which was even acknowledged by Hillary Clinton even more than her Democratic predecessors. However, her stand looked ridiculous considering her husband’s past administration which baited white voters at the expense of the blacks’ interests. As much as it is easy to excuse Hillary for her husband’s sins, her turnaround at the 2008 campaign and stating to support white Americans worked against her. The white supremacy can be felt across the board even through the ignoring of the blacks during employment, health, and housing.
The issue of political correctness is another way the leftists have managed to suppress the blacks and embrace white supremacy. The crisis is further fueled by how journalists cover the campaigns. A New York Times essay by Mark Lilla is an example of how journalism affects the politics of America. The article talks more about the whites and despite Obama’s integral role, his name does not appear amongst politicians doing identity politics. It appears that what appeals to the whites is more ennobled in coverage of politics.
In conclusion, the whiteness ideology has benefited many white leaders before, but Donald Trump’s own rise is unique. The American history points to slavery as a contributing factor to racism in modern politics alongside issues of class. White supremacy has grown Trump and propelled him to power, but the talk about his bigotry has furthered his political growth. The unique elements of Trump’s rise to power make him look like the
