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

omprakash patilCan 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.nooneperfectCan weight is considered as axial load??? -
omprakash patilTorque will be zero as load acting parallel to axis..

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