PSAD 18: Conjugate Beam Method Video Transcript Situation 1 – Refer to FIG. TOS 001 A 5 kN load is applied at the free end of the cantilever beam ABC as shown. Given: E = 200 GPa I = 400 x 106 mm4 1. What is the deflection at point B? a. −0.667 mm b. −0.500 mm c. −0.417 mm d. −1.333 mm 2. What is the slope at point B? a. 0.000573 b. 0.00735 c. 0.000357 d. 0.000375 3. What is the maximum deflection? a. −0.667 mm b. −0.500 mm c. −0.417 mm d. −1.333 mm Solution: Drawing the elastic curve and the moment diagram by parts with moment center at the fixed support, Solving for y1 and y2, y1 = (−5)(4) = −20
