Explanation / Answer

Part A: Since there is no axial force in the beam, normal force at C=0

Part B:

Let us determine the reaction force at A by considering moment equilibrium at support B

14RA-(480*8)+(253*8)=0

RA=129.71 lb

Shear force at C = 129.71-480=-350.29 lb

Part C : Moment at point c = (129.71*10)-(480*4)=-622.9 lb-ft

Part D: Since there is no axial force in the beam, normal force at D=0

Part E:Shear force at point D = F3=253 lb

Part F : Moment at D = 253*2=-506 lb-ft
