A 1 inch diameter bar machined from AISI 1035 CD Steel is subjected to an alternating bending stress between 1 and 51 kpsi at 400 C. Find the factor of safety guarding against static failure and either the factor of safety guarding against a fatigue failure

Ariver flows from north to south at 8 km/h. a boat is to cross this river from west to east at a speed of 20 km/h (speed of the boat with respect to the earth/ground). at what angle (in degrees) must the boat be pointed upstream such that it will proceed directly across the river (hint: find the speed of the boat with respect to water/river)? a 288 b. 21.8 c. 326 d. 30.2

Avolume of 2.65 m3 of air in a rigid, insulated container fitted with a paddle wheel is initially at 264 k, 5.6 bar. the air receives 432 kj by work from the paddle wheel. assuming the ideal gas model with cv = 0.71 kj/kg • k, determine for the air the amount of entropy produced, in kj/k

What is a monomer? how do they form a ploymer from the view point of chemical bonding?
