Weight As Axial Load

A Stepped bar is hung from the ceiling as shown in the figure. The cross section of AB=500 mm^2 and that of BC=200 mm^2.
Assuming that the density of both rods are same and equal to 7500 kg/m^3.Find the axial force at a section A-A' just above B.
Take g= 10 m/s^2.
A downward force 20 N is acting at B and a force of 5N at C is acting upwards.

Ans.
1. 32.5 N
2. 22.5 N
3. 90 N
4. 100 N

    nooneperfectCan weight is considered as axial load???

    Certainly it is, provided the axis is vertical. Otherwise there will be a torque component and an axial load component, which can be determined by resolving the forces along the axis and perpendicular to it.

    Torque will be zero as load acting parallel to axis..

    Torque will be zero as load acting parallel to axis.And answer will be 22.5 N in AB section using F=m.g
