I need calculation for Compression is -14.37 and tension is 7.29 Start with the support reactions. On each joint there is -0.5K. On the ends there is -0.25K. Then you check bending, tension, and deflection.

hi,

3. 12.15, you are correct.

4.2.01, your first digit is correct,

hope this !

the f

last graph i believe

step-by-step explanation:

worked it out i believe

hello from mrbilldoesmath!

answer:

(7 x + 6 y) (49 x^2 - 42 x y + 36 y^2)

discussion:

the trick is to recognize that 343 = 7^3 and 216 = 6^3 and, in general,

a^3 + b^3 =   (a + b) (a^2 - a b + b^2).

in our case

343x^3+216y^3   =   (7x)^3 + (6y)^3

so take a = 7x and b = 6y in the above equation to get the answer.

you,

mrb
