Atwood's Machine

Assuming that Atwood's machine target and task: 2 (m 1 + m 2) h = (MA + B) t 2 (m 1 + m 2) are constants, the values ​​of constants A and B can be derived therefrom Draw a graph. Then, please investigate what the value should be like. METHOD: Set a pulley with two masses, hanging strong yarns / strings on both sides of m1 and m2 so that m2 is about 5 meters from the ground when m1 is placed on it. When m 2 = 280 g and m 1 = 250 g, an accurate time for m 2 to pass through the distance "h" to the ground is obtained.

Dynamics: Newton's motion law and its application to objects hanging with strings; Atwood's machine; blocks touching each other on a horizontal plane without friction; apparent weight of elevator - pulse - linear momentum conservation law (only) statement) - Work - force - energy - definition and units - sports expression and KE - work - energy theorem - energy conservation law - example - vertical projection and free fall. Collision and center of gravity: collision of two objects in one dimension - collision of elasticity and elasticity - stationary object - two objects moving in the same direction and opposite direction - recovery factor, height equation obtained by free fall on the field Equation Rebound rear

Atwood's article starts with an excerpt from a letter. The letter comes from the Michigan State Quarterly Review and asks him to submit an article on the theme of women's "tolerance" to Atwood. The cynical tone of Atwood's article shows her reaction to this request and her ridicule of women's objectivity. By calling her body "topic", Atwood emphasized the central idea of ​​her essay, traditionally women are seen as things. By describing each adjective of your body and then repeating "theme", "theme" embodies the body and becomes human. When it actually becomes a "topic", the body "like meat and blood". . This combination of irony and repeat is still one of Atwood's techniques for seriously creating humor while considering her theme.
