ok I got it now... I was supposed to plug in the roller support reaction into the FBD of AC on top of Cy and Cx...that was throwing the whole thing off... thanks again.

Thank you for the reply. So if I take the entire frame would C then become a roller and not a pin?

Homework Statement The two-member frame (see picture attached) supports the 200-lb cylinder and 500 lb–ft couple moment. Determine the force of the roller at B on member AC and the horizontal and vertical components of force which the pin at C exerts on member CB and the pin at A exerts...

ok thank you very much...

I wrote it exactly as it was given.

im just not sure if this means that its -6.216i for the position vector of AD or -6.216i for the actual x component for the tensile force...I just don't see how it could be -6.216 for the tensile force when the magnitude is 14000 lbs. Having the x component of the position vector of AD...

Homework Statement For cable AD it is known that the magnitude is 14 kips, x-component has a value of -6.216, the direction angle in the z-direction is 83.63°, and Fy is less than zero. Find forces in Cartesian vector form, coordinates of point D if it lies on the x-z plane and point A is (0...

thanks for the replies guys...

yeah sorry i worded the problem wrong...still, thank you for all the replies...ill do a better job next time.

Homework Statement If F_1 = 100N , F_2 = 120N and F_3 = 80N , determine the magnitude and coordinate direction angles of the resultant couple moment. Homework Equations M=Fd M=r x F MR=Ʃ(r x F) The Attempt at a Solution I found the couple moment for each force: M1=F1d=100(0.2) or...

right I know how to set up the problem... but once I try to solve for d the algebra just throws me off.

sorry it should be s=*lstretched-l0...

the force of the spring is k(s)... k=600 is given, and I know s = l - l0; therefore Fspring=600(l-l0). l0 is also given and equals 1.5m so the equation becomes 600(l - 1.5). Looking at the triangle the two springs create with the wall we can deduce that l (length of the stretched spring) is...

anyone?
