Draw a sketch:
T1================210N======710N=======T2
Take moments about the left:
T2*2.8 - 210*1.4 - 710*1.8 = 0
Solve for T2
Take moments about the right:
-T1*2.8 + 210*1.4 + 71-*(2.8-1.8) = 0
Solve for T1
i keep coming up with the wrong answer for T1. i am getting 358.57 and its wrong.
Unless your question takes T2 as the first answer, which is supposed to be (710+210)-358.57 = 561.43.
If that's not the case, verify
1. instruction for rounding of answers (to the nearest newton, two decimals, etc.)
2. order of the answers (which should add up to 710+210.
3. Check that the numbers posted correspond to the questions on the computer.
4. Sometimes after a wrong answer, the qustion gets modified by the computer. Make sure that did not happen.
