10.A solid circular titanium control rod at 7,000 lb axial tension force, stress must not exceed 42,000 psi. Assume that the modulus of elasticity of the titanium is
16,500,000 psi and that the rod must elongate no more than 0.20 in. Determine (a)
the minimum rod diameter (precision 0.00) and (b) the maximum rod length.
(precision of 1)

step-by-step explanation:

you add up all the numbers together to get this answer

to find perimiter, add all the sides.

60 5/6 + 54 1/3 + 59 1/3 + 56 1/6.

goup like terms:

(60 5/6 + 56 1/6) + ( 54 1/3 + 59 1/3) = 117 + 113 2/3

56 + 60 =   116. 5/6 + 1/6 = 6/6 = 1/ 116 + 1 = 117

54 + 59 = 13. 1/3 + 1/3 =2/3. 13 + /3 = 113 2/3    

117 + 113 2/3 = 230 2/3

answer: 230 2/3
