The linearly elastic planar structure shown in the figure is acted upon by two vertical concentrated forces. The horizontal beams UV and WX are connected with the help of the vertical linear spring with spring constant k = 20 kN/m. The fixed supports are provided at U and X. It is given that flexural rigidity EI = 105 kN-m2, P = 100 kN, and a = 5 m. Force Q is applied at the center of beam WX such that the force in the spring VW becomes zero.
The magnitude of force Q (in kN) is __________. (round off to the nearest integer)
For the square steel beam cross-section shown in the figure, the shape factor about Z - Z axis is S and the plastic moment capacity is Mp. Consider yield stress fy = 250 MPa and a = 100 mm.
The values of S and Mp (rounded off to one decimal place) are
Which of the following statements is/are correct?
Consider a beam PQ fixed at P, hinged at Q, and subjected to a load F as shown in figure (not drawn to scale). The static and kinematic degrees of indeterminacy, respectively are
