Arod loaded in tension with an axial force of p- 1200 n and circular cross-sectional area of a undergoes a nominal stress ofo p/a pia. 1(a)-using a design factor of 3.0 and a material strength of 120 kpa, determine the minimum diameter of a solid circular rod. 1b)-using a proper table, select a preferred diameter and determine the rod's factor of safety 1(c) -the following variations are assumed: the rod's diameter is manufactured within ± 3% ofits nominal dimension, the load is known within± 4% ofthe nominal load, and the material strength is known within 6% of the nominal strength value. if the designer is using nominal values and a stress equation, determine what design factor should be used so that the stress does not exceed the strength. the load application would be considered dynamic (a sudden increase from a zero value) while eccentricity is not considered here. note: the positive and negative values are the maximum and minimum values allowed in the manufacturing, respectively

Acetic acid  /əˈsiːtɪk/, systematically named  ethanoic acid  /ˌɛθəˈnoʊɪk/, is a colourless liquid  organic compound  with the  chemical formula  ch3cooh (also written as ch3co2h or c2h4o2). when undiluted, it is sometimes called  glacial acetic acid.  vinegar  is no less than 4% acetic acid by volume, making acetic acid the main component of vinegar apart from water. acetic acid has a distinctive sour taste and pungent smell. in addition to household vinegar, it is mainly produced as a precursor to  polyvinyl acetate  and  cellulose acetate. it is classified as a  weak acid  since it only partially  dissociates  in solution, but concentrated acetic acid is corrosive and can attack the skin.acetic acidnamespreferred iupac nameacetic acidsystematic iupac nameethanoic acidother namesvinegar (when dilute); hydrogen acetate; methanecarboxylic acid[1][2]identifierscas number64-19-7  3d model (jsmol)interactive image3dmetb00009 reference506007chebichebi: 15366  chemblchembl539  chemspider171  drugbankdb03166  echa infocard100.000.528ec number200-580-7e numbere260  (preservatives)gmelin reference1380iuphar/bps1058keggd00010  meshacetic+acidpubchem  cid176rtecs numberaf1225000uniiq40q9n063p  un number2789inchiinchi=1s/c2h4o2/c1-2(3)4/h1h3,(h,3,4)  key:   qtbsbxvteameqo-uhfffaoysa-n  smilescc(o)=o
