    Statics: Two-member Frame

    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.

    Statics: Two-member Frame

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

    Statics: Two-member Frame

    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...

    Statics: Forces in Cartesian Vector form

    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...

    Statics: Forces in Cartesian Vector form

    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...

    Statics- Resultant couple moment

    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...

    Equilibrium and displacement of a Particle

    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...

    Equilibrium and displacement of a Particle

    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...
