The frame shown in figure below is supported on pivots at A and B. Each member weighs 50 kN/m. Compute the horizontal reaction at A and the horizontal and vertical components of the reaction at B. RAH SOX12)=600 3 E C 600 50(10)=500 200 kN R Rav

The reaction at the support A and B is?

3. Using the given figure below, determine the reaction of strut member DE and determine the reaction of pin at joint C (use member ABCD). - 2.5 m - 2.5 m 3.5 m C D F 1 m E 3 m 50 A 100 kN

A load P is supported by a structure consisting of rigid bar ABC, two identical solid aluminum alloy [E = 73 GPa] rods (1), and a solid bronze [E = 105 GPa] rod (2). The aluminum rods (1) each have a diameter of 8 mm and a length of L₁ = 1.5 m. They are symmetrically positioned relative to middle rod (2) and the applied load P. Bronze rod (2) has a diameter of 16 mm and a length of L₂ = 1.0 m. If all bars are unstressed before the load P is applied, determine the normal stresses in the aluminum and bronze rods after a load of P = 66 KN is applied to the rigid bar.
