I have tried to do the problem multiple amounts of time but I never seem to get the correct answer. For surface 1 its suppose to be 350 Nm^2/c and surface 2 is suppose to be 460 Nm^2/c. This is what I have gotten so far:

1: EACos(pheta) 250(1.7)(cos 55)= 9.4028 Nm^2/c

2: EACose(pheta) 250(3.2)(cos 35)= -722.95

Please help with anything you can!

A) 250(1.7)cos35

B) 250(3.2)cos55

this will work, just did it for my homework and they are correct. My E and A are different but the theta was the same.

**CombatVetUSMC**, Tuesday, July 10, 2012 at 1:39amchanged my login from the above entry.

A) 250(1.7)cos35 = 348.13 Nm2/C

B) 250(3.2)cos55 = 458.86 Nm2/C

Hopefully this works for you
