Let's investigate the internal stresses of a laminated beam subjected to the 3-point bend test. compare the distribution for the following cases (a) [0,+-45, 90]s and (b) [90/+-45/0]s. in this case, plot latex: \sigma σ x/latex: \sigma σ max using the following properties of unidirectional graphite/epoxy composite. compare the maximum stress in the plot with that found in the equation for maximum stress (refer to the slide titled inplane stress).

e11 = 126 gpa
e22 = 12.2 gpa
g12 = 7.6 gpa
v12 = 0.3
explain what you notice about these plots. is this what you would expect to see? why or why not? how does it compare to the case of a homogeneous beam (i. e., a beam made from one material)?

freezing

deposition

condensation

explanation;

melting also called fusion is the process where solid becomes liquid, sublimation is the process where solid becomes gaseous without first changing to liquid, deposition involves change from gaseous to solid state, freezing involves change from liquid to solid, boiling or evaporation involves change of liquid to gaseous state, while condensation is the change from gaseous state to liquid state.

endothermic reactions involves absorption of heat from the surroundings or the environment while exothermic reactions involves loss of heat energy to the surroundings.

in this case, sublimation, evaporation and melting are endothermic reactions (gain energy from the environment) while, freezing, deposition and condensation are exothermic (loss of energy to the surroundings) reactions.

multiple allele inheritance is traits controlled by more than 2 alleles (ex: pigeons having 3 alleles of one gene govern their feather color).
