工程力学(Ⅱ)期终考试卷(A)题号三四五六总分题分得分一、填空题(每题5分，共25分)的规律转动，其上一小环M将杆AB和半径为R(以m计)的固定大圆环连在一起，若以0为原点，逆时针为正向，则用自然法表示的点M的运动方程为2.平面机构如图所示。已知AB//0O,且AB=O₁O₂=L,AO=BO₂=r,ABCD是矩形板，AD=BC=b,AO₁杆以匀角速度□绕0轴转动，则矩形板重心C'点的速度和加速度的大小分别为v=r_,a=rl并在图上标出它们的方向。3.两全同的三棱柱，倾角为□,静止地置于 o转动的角速度为□,角加速度为□,若将惯性力系向0点简化，则惯性力系的主矢为me□,meP;惯性力系的主矩为各矢量应在图中标出。和’5.质量为m和’为,若物体受到干扰力FHin(wt)二、计算题(本题15分)图示平面机构中，杆0A绕0轴转动，设O₂B=L,在图示□=30°位置时，杆故又故又OA的角速度为□,角加速度为零。试求该瞬时杆O₂B转动的角速度与角加速度。解：以铰链为动点，杆O₁A为动系。有,(逆钟向)[6分][10分](逆钟向)[15分]三、计算题(本题15分)□D=□C=60°,杆OA的角速度为φ,角加速度为α₁。试求在该瞬时，杆O₂B的角速度和角加速度。杆AB作瞬时平动。即0=0Vg=V₄=Ro₁[3分](逆钟向)[6分]选点A为基点，则点B的加速度向AB方向投影，得-acosφ+asing=acosφ+asing分]解得(方向如图)[15分]四、计算题(本题20分)在图示机构中，已知：斜面倾角为β,物块A的质量为mi,半径为r,绳的两端直线段分别与斜面和水平面平(2)该瞬时水平面对轮C的静滑动摩拐五、计算题(本题10分)六、计算题(本题15分)量为m,小环B质量为m,弹簧的刚度系数为k,自然长度为d。试用第二类拉格朗日方程建立系统的运动微分方程，以x和□口为广义坐标。解：以x和□口为广义坐标，系统在一般位置时的动能和势能代入第二类拉格朗日方程可得系统的运动微分方程为：Tworegulationspromulgatedforimplementstrategicplan,implementationinaccordancewiththerulessupervisionofmajorinitiatives.Thesupportingeachother,the<code<rule>aroundthepartydiscipline,disciplinaryrulerverticalgauge,drawthepartyorganizationsandmembersdonottouchthe"bottomline".thefirstpartintroducestwopartyRevisedregulationstheinterpretationofthetwofundamentalprinciplesoftherevisionoflawsandregulpartonhowtograspregulationsoftheparty.<code>and<RegulationsrevisedthenecessityandrevisedhistoryoftheCPCCentralCommitteetheamendmenttothepartylawsandregulatirevisionworklastedaYears,poolingthewisdomofthewhichreflectstheunityofiadheretotheparty'sleadership,tosolvethemassesofthepeoplereflectafocusontheproblem.Thenewrevisionofthe<code>and<rule>,reflectstheparty's18andtheeighthsessionofthethird,thespiritofthefourthplenarysession,reflectingtheexperienceofimplementingtheGeneralSecretaryXiJinpingseriesofregulationsofthepartynee<in1997Leadersasrevised,thepromulgationandimplementationofJanuary2010,tostrengthentheconstructionofthecontingenleadingcadresplayanimportantrole.Butwiththepatomanagethepartystrictlyadministeringthedeepening,hasnotbeenableto"hardtoremember,andalsodifficulttpractice;thesecondisconciselypositiveadvocatedbytherequirements;thethirdisbannedtermsanddisciplinelChineseCommunistPartydisimplementation,tostrengthentheconstructionofthepartyplayveryimportantrole.Alongwiththedevelopmentofthesituation,whichmanyprovisionshavebeenunabletofullymeetthecomprneeds.OneisJilaw,morethanhalfoftheprovisionsandRepetition;twoisthepoliticaldisciplineregulnotprominent,notspecific,forviolationofthepartyconstitution,damagetheauthorityofPartyConstitutionofpursue;thirdisthemaindisciplinefortheldoesnotcoversituation,needto<thecriterionofacleanandhonestrelevantregulationsfirstamendment.Byrevising,reallyputtheauthoritythepartytreeandcallupthemajorityofandcadresofthepartyconstitutionofprocesstheCentralCommitteeoftheCommunistXiJinping,generalbooksrecordedintheFifthPlenaryclearinstructions.Accordingtothecentraldeployment,StandingCommitteeoftheCentraheldaspecialmeetingtostudytworegullistentopartoftheprovince(area)secretaryPartycommittee,SecretaryoftheDisciplineInspectionCommission,partofthepeople,viewsofexpertsandscholarsandgrassrootspartyCommitteeoftheCommunistPartyofChina,on7September2015,thegeneralofficeoftregions,municipalities)Party,thececommissions,stateministriesandcommissionsoft(party),theGeneralPoliticalDepartmentofthemilitary,every3peopleorganizationofPartyoftworegulationsBureauStandingCommitteeandthePoliticaCommitteeoftheCommunistPartyofChinaformallyissuedtworegulations.Cansay,twolawsamendmthewisdomofthewholeparty,embodiestheparty.Second,principlesoftwopartyregulationsrevisionworkandimplementtheparty'seighteen,tespiritoftheFourthPlenarySessionoftheEleventhquiteinfrontofthelterm,advanceasawhole,withBuXiudingindeprule>and<rule>.Mainprincipleis:first,adheretothepartyconstitutiontofollow.Thecconsciousness,maintainingtheauthorityoftheInearly2015heldtheeighthCommissionforofthe16thCentralCommittee,Xirules,butalsothegeneralrules."therevisionofthe<establishedforthepurposeofcombiningruleofvirtueisaccordancewiththeparty.ThePartyofruleofvirtue"de",mainlyreferstotheparty'sidealsandbeliefs,excellenttraditionaldiscipline,focusingonthemoreaction,thestrictpartydisciplineandpracticeresultstransformationfortheintegraobservemoralanddisciplinerequirements,forthemajorityofPartymembersandcadThird,insistonthepartyatthepresentstage,themainproblemsofPartyabidebythedisciplinepoliticalrules,organizationanddisciplineDisciplinaryprovisions.Notonepacereachsthedesignatedposition,focusingoninlinewithreality,effective.Aftertherevisionofchangesingraspseveralkeyproblemsdiscipline",remamendment<cases>.Thrprominentkeyminority,seizetheleadershipofthepartymembersandcadresistsimplify,andstrivetoachieveconcise,easytoueasytoremember.Therevised<code>istherulissuedtoallmembersofthepartyandtheNationalPeople'ssolemncommhonestadministrationconsistsof4pa3600words.Aftertherevisionofthe<code>,atotalofPart3memberslow-costcleanansentiments,suchasrequirements,strongtoneofself-discipline,Thehigherrequestfor6permanentBaotheparty'sadvancednatureandpurity,toreflecttherevisedstandardsrequirements.Membersof"cheapandrofingeredself-disciplinenormsfortheleadepartymembersandcadresandotheraspectsoftheleadershipofthepartymembersandcadresofthe"fournorms"<><normnorm."ThePartyleadingcadrecleanfingeredstotalofeight,co
