### The beam ( A B C ) is supported by a roller at ( B ) and a pin joint at ( C ). A uniformly distributed load with magnitude ( w=1500 mathrm{~N} / mathrm{m} ) is applied as shown in the figure. Take ( E I=120,000 mathrm{Nm}^{2} ) and ( L=1.2 mathrm{~m} ). a) Calculate the support reactions at ( B ) and ( C ) b) Select the conect boundary
