2. 

The work platform supports an 80-kg man having a mass center at G. Determine the axial force, shear force, and bending moment at point E of the telescopic column AB due to the load of the man only.

[A]. AE = 785 N C, VE = 0, ME = 785 N-m
[B]. AE = 785 N C, VE = 392 N, ME = 0
[C]. AE = 785 N T, VE = 392 N, ME = 0
[D]. AE = 785 N T, VE = 0, ME = 785 N-m

Answer: Option A

Explanation:

No answer description available for this question.

Moment about E = 80*9.81*1.
= 785Nm.

Axial force = 80*9.81N.
No shear force.

Yes, the force is eccentric but we can replace it by the axial force and moment.
