    Can the Plastic Moment be smaller than Elastic Moment?

    Homework Statement Stress = 320 MPa Max Elastic Moment = Stress*Z Max Plastic Moment = Stress*S Solve the maximum moments and compare the % increase Beam is an I beam with dimensions: (b and d) Top Flange = 25*10 web = 10*180 Bottom Flange = 200*8 Homework Equations see above The Attempt at...

    Does Angling a pin support on a truss change anything?

    Yeah I am concerned with just the external reactions of the pin support. Like in that picture I added, would tilting the support 30 degrees underneath the truss create a horizontal reaction? or would it still be 0 because there is no horizontal load? PS. there are point loads on the truss at...

    Does Angling a pin support on a truss change anything?

    Okay so, imagine a basic truss that has a roller on the left side and a pin on the right. The pin on the right it angled at 30 degrees so instead of it sitting under the end perpendicular to the truss, its tilted by 30 degrees. Does tilting the support change the external reactions?

    Does Angling a pin support on a truss change anything?

    Homework Statement If you had a simple 2D truss with a pin and a roller support, would making the pin on a 30 degree incline change the supporting reactions? Homework EquationsThe Attempt at a Solution Can't see why since it still supports a horizontal and vertical, don't know hwy the angle...
