Question 4 (25 p.): There is a simple beam in Figure with triangular distributed load whose magnitude is equal to 3 kN/m at roller support "B".
a) Draw the free body diagram for the beam shown in Figure and determine the reaction magnitudes and directions for each support (Connections; at "A": pin connection, at "B": roller)
b) Write equations of internal forces (Normal Force, Shear Force and Moment) using the Method of Sections for the beam.
