In relation to the Neutral Axis of a beam, which of the following are correct (there is more than one correct answer) ?
Its the center of gravity of the cross sectional area
Its the plane where stiffness is zero
Its the plane where zero deflection occurs
Its the plane where zero deflection occurs
Its the plane where zero stress occurs
It is possible to remove material located on the edges of an I-Beam (away from the N.A.) without affecting the Stiffness and Strength of the Beam ?
Yes it is
No it is not
A beam with a rectangular cross section measures 150mm wide by 200mm high. What is its second moment of area. (Only one correct answer) ?
1x10-4 m4
100x106 m4
5.625x10-8 m4
4x10-5 m4
How does a strain gauge measure strain ?
Who knows ?
It expands and contracts with temperature and thus measures strain
The stress is measured via a change in force and then converted into strain
It converts a minute change in resistance into a change in length hence strain
