The buckling load P = P, for the column AB in the figure, as Kr approaches infinity, become a π²EI L where a is equal to P flexural rigidity, El DB im torsional spring of stiffness Kr

The horizontal beam is supported by a pin at A and the pin-connected link BC. It has a uniformly distributed loading w = 2.6 kN/m as shown in the figure. All the pins are in double shear and have a diameter of 20 mm. Determine the max shear stress in the pin at C. Input your answer as a value only in MPa to one decimal place without +/- sign. W 1.5 m 2 m B 1m

From the following armor, determine the following: Reactions in A and F. The internal forces at node C. (Indicate whether the forces are in compression or tension.)  The internal forces in the elements CH, CD and HI. (Indicate if the forces are in compression (C) or tension (T)). Draw the respective free-body diagrams. Consider the following:  A and F are supports. the angles a, B, y are angles of 90, 60 and 30 ° respectively (Check image pr2 for the image of the armor) (Check image pr2.2 for the values to be used)
