Answer 1

Transcribed image text: Using finite element method, determine the reaction moments at the fixed ends of the beam as shown. The beam is divided into two elements. At node 2, a downward force and an ACW moment are applied. Take the modulus of elasticity to be 150 GPa and the moment of inertia of the cross section as 0.001 m^. 35 kN-m 5 m 3 5 m 1 2 50 kN a) Reaction moments at nodes 1 and 3 = 71.25 kN-m ACW and 53.75 kN-m CW respectively. b) Reaction moments at nodes 1 and 3 = 17.5 kN-m ACW and 17.5 kN-m ACW respectively. c) Reaction moments at nodes 1 and 3 = 42.5 kN-m ACW and 25 kN-m CW respectively. d) Reaction moments at nodes 1 and 3 = 105 kN-m ACW and 70 kN-m CW respectively.
