ASSIGNMENT 2Textbook Assignment:“The Screw,” chapter 5, pages 5–1 through 5–4; “Gears,” chapter 6,pages 6–1 through 6–8; “Work,” chapter 7, pages 7-1 through 7–6; and“Power,” chapter 8, pages 8–1 through 8–4.2-3.How do you find the theoreticalmechanical advantage of ajackscrew?1.Divide the amount of resistanceby the amount of effort2–1.What is the pitch of the screwfigure 2A?1.1/16 in2.1/2 in3.1 4/7 in4. 3inin2–2.Upon which measurements does thetheoretical mechanical advantage ofa jackscrew depend?1.Pitch and length of the screw2.Length of the jack handle andradius of the screw3.Pitch and radius of the screw4.Length of the jack handle andpitch of the screwrequired to overcome theresistance2.Multiply the length of the jackhandle by the radius of thescrew and then divide by thelength of the screw3.Multiply the length of the jackhandle by 2rr and then divide bythe pitch of the screw4.Divide the length of the jackhandle by 27r and then multiplyby the pitch of the screw2–4.High friction losses are built intoa jackscrew in order to prevent the1.screw from turning under theweight of a load as soon as thelifting force is removed2.screw from becoming overheatedwhen a load is being lifted3.threads of the screw from beingsheared off by the weight of aload4.jack from toppling over as soonas the lifting force is removed2–5.If a screw has a pitch of 1/16inch, how many turns are requiredto advance it 1/2 inch?1. 22.83.164. 3212
