Consider a sample of homogeneous, isotropic material of poisson’s ratio º and yield stress ¾y confined in a rigid cylinder, as depicted in fig. 2.2. a single stress component is applied to the material and it is assumed that there is no friction between the sample and the enclosure. (1) find the stress level ¾3 for which the sample will yield as a function of ¾y and º if the material obeys tresca’s criterion. plot your results. (2) find the stress level ¾3 for which the sample will yield as a function of ¾y and º if the material obeys von mises’ criterion. plot your results. use a range of poisson’s ratios º 2 [0; 0: 5].

answer: what are the answer choices?

step-by-step explanation:

answer: cos [   arcsin (3/5) - arccos (1/2) ] =

step-by-step explanation: × = 3/5 = 0.6--> x = 36.87 and x = 180 - 36.87 = 143.13 deg

cos y = 1/2 --> y = +- 60 deg a. cos (x - y) = cos (143.13 - 60) = cos 83,13  

=

0.12

b. cos (36.87 - 60) = cos (-23.23) = 0.92

answer: 486in^2

step-by-step explanation:

statement #3: proof- ang is congruent to ang ecd : angles are congruent.  

step-by-step explanation:

1: the missing angles in statement #3  

a.) acb  

reason- the reason why the answer is acb is because angle ecd and angle acb are both the same size *that's what the word congruent means this is really simple.  

2: the missing word in reason #3  

c.) vertical  

reason- the reason why the answer is vertical is because the angles in that diagram on figure 2 is slanted, which is vertical, and the e and a both lay on vertical lines. along with the other's, but e and a are the 2 main points you want to focus on. and c is kind of like your starting point, because c is for both angles, not just one.  

i hope that was and understanding.
