Explanation / Answer

Part A:

Normal force at B=F1+(4/5)F3

= 290+(4/5)*455 = 654N

Part B:

Shear Force in x direction at B=F2 = 370N

Part C :

Shear Force in z direction at B = (3/5)F3 + (2+2)*10*9.8 = (3/5)*455 + 392 = 665N

Part D :

Resultant torque at B = F2*2 = 370*2=740Nm

Part E:

Bending moment along x direction=2*(3/5)*F3 + F1*2 + (10*2*9.8*2)+(10*2*9.8*1)= 2*(3/5)*455 + 290*2 + (10*2*9.8*2)+(10*2*9.8*1) = 1714Nm

Part F:

Bending moment at B along z direction = F2*2 = 370*2=740Nm
