    Bending of a curved beam to protect a tank nozzle

    Yes you are correct. I'm interested in the behavior of the flat bar that has been curved and welded to the tank to create a type of cage. A simplifying assumption would be that the force is directed at the center of the curved bar (L/2). This is a little beyond the statics/dynamics class I took...

    Bending of a curved beam to protect a tank nozzle

    In the tank building industry some pressure vessels use curved pieces of flat bar, welded to the tank, to protect nozzles in the event that the tank rolls. I'm trying to determine how thick the flat bar should be for a given length so that it won't bend too much and allow a nozzle to be damaged...

    Design Considerations for Bending of Irregular Shaped Brackets

    I made an initial guess for the thickness to be 1/2" and used the equations for a short column located in Marks' Standard Handbook for Mechanical Engineers. So using this method I have determined that if my b dimension (thickness) is 1/2" than my other dimension must be 6.68". How do I decide if...

    Design Considerations for Bending of Irregular Shaped Brackets

    The force in AC = Cy(13.9/11) = 41700 lb. So now that I want to make sure this member is thick enough to withstand this compression force without buckling do I use the equations for a column? You mentioned that a slenderness ratio of 15 should suffice. Does it mean that the radius of gyration...

    Design Considerations for Bending of Irregular Shaped Brackets

    Statics is definitely not my strong suite and I appreciate your patience. My understanding of a triangle of forces is that the resultant of 3 vector forces is equal to 0. When I draw these vectors (attached picture) and see that the B vector only has a horizontal component it follows that By =...

    Design Considerations for Bending of Irregular Shaped Brackets

    After doing the joint analysis I realized that Cy was initially pointing the wrong direction. This better?

    Design Considerations for Bending of Irregular Shaped Brackets

    I performed joint calculations and determined that Cy is actually pointing down. Is this correct? I read your comments but I'm still not sure how to calculate By and Cy. You mentioned setting the bending moment at A in AB and AC to be zero but the bending of this truss (really a solid gusset) is...

    Design Considerations for Bending of Irregular Shaped Brackets

    This is what I've got so far. I know I must be forgetting something because I don't have enough info to solve for By and Cy. Can you point me in the right direction? Thanks

    Will a 304 SST Plate Bend Under a 460 Lbs Load at a 21 Degree Angle?

    Daever: Can you point me in the general direction for the calculations? I know you say it is intensive but I'm trying to determine bending in a gusset similar to this question posted by Fishburn7. If anybody can point me in the right direction for this type of "plate bending" I would appreciate...

    Design Considerations for Bending of Irregular Shaped Brackets

    So the truss would look like the following picture then? The force in each member would need to be solved for?

    Design Considerations for Bending of Irregular Shaped Brackets

    I was thinking about cutting it horizontally and treating it as multiple beams but I don't know if that would be a good method to use or how that would work since, after the first beam, the length wouldn't extend to the location of the point force. Any suggestions?

    Design Considerations for Bending of Irregular Shaped Brackets

    I am looking for an equation (or method to develop the equation) for bending of an irregular shape. I have only been able to find bending equations for beams. The attached picture shows the shape of the gusset being bent and the location of the force. If this were a beam it would be a cantilever...

    Beam bending under a uniformly distributed load

    Homework Statement I have a bumper and I am trying to determine whether or not the rectangular tubing I am using to build it is strong enough to withstand a given load (rear end collision). The horizontal member is 4x3x.1875 tubing (4" base, 3" high, 95" long). Two 3x3x.1975 tubes are used as...
