Activity 2: Use Virtual Work method to solve for the slope at joint F, horizontal deflection at joint at F, and vertical deflection at joint E of the rigid frame shown. 30KN с 80 KN 3m DV 2m E 21 FZ I 3m 2m B 21 3m 20KN

There is a statically indeterminate beam in which the horizontal force at the left and right ends (points A and D) is zero, and the vertical force is shown in the figure below, The flexural stiffness of the beam section is constant El: (a) Find the slope (Slope) of point B after deformation. (b) Find the vertical displacement of point C (Deflection). *correct answer is (a) 89.9 kips-ft2/El clockwise (b) 1656.21kips-ft3 /El down But I want to calculate the process, thank you

The truss structure shown contains 15 pin-connected elements each with a cross-sectional area of 200 mm² and a modulus of elasticity of 210 GPa. Determine the vertical deflection of point H using Castigliano's method. D 3 m E 3 m 3 m F 3 m B H 3 m 8 kN A

QUESTION 2 - BEAM For the beam shown below, determine the vertical deflection at point B by using the virtual work method. EI is constant. -5 ft A -5 ft 12 k Į -5 ft B -5 ft- 70 k-ft Fig. 2
