The basquin law for an alloy tested at r = −1 is n_f^b ((∆σ))/2= c
at a δσ of 300 mpa, nf is 105 cycles, and at a δσ of 200 mpa, nf is 107 cycles.
(a) determine the values of the constants b and c.
(b) what is nf for a stress range of 250 mpa?
(c) if a specimen is cycled at 250 mpa for 5 × 105 cycles, how many additional cycles based upon the miner-rule will the specimen be able to sustain at a stress range of 200 mpa?

if the concentration of products is decreased, the equilibrium will shift toward the products). add an inert gas (one that is not involved in the reaction) to the constant-volume reaction mixture: this will increase the total pressure of the system, but will have no effect on the equilibrium condition.

explanation:

each  column  of the  table  is called a group. elements in a group share similar properties. groups are  read  from  top  to  bottom. metal. metalloid. nonmetal. solid. liquid. gas. fe. hg. o.  2. 3. 4. 5. 6. 7. 8. 9.  2. beryllium. 9.012. 4.  sodium. 22.990.  11. 3.  magnesium. 24.305.  12.  potassium. 39.098.  19. 4.  calcium. 40.078.  20. i guess  i
