How do you convert steal yield and tensile strength to pounds?
If you load a beam in tension or compression only ( pull or push) then you multiply the tensile yield or ultimate strength by the area of the beam cross section. Thus applies to a simple beam (bar) only. If you load the beam any other way, such as bending or twisting, or perpendicular to its axis you need to use formulas from an engineering strength of materials course or handbook.
Why we use double reinforced section?
when section of the beam is restricted and the moment due to incoming load is not resisted by moment due to concrete then we have to provide reinforcement in compression zone also to take this extra incoming load
What is common about the location of the maximum moment along the beam in each loading case?
It is the center of the beam, if the beam is supported at both ends.
How do you measure the resisting bending moment of a reinforced channel frame?
The resisting bending moment is the product of the yield strength (of the beam material) and the section modulus of the beam. The RBM thus combines the material attributes as well as the geometric attributes of the beam and gives a useful metric to compare different beams irrespective of material or sectional geometry.
Plastic section modulus for beam sections- Any computer program for calculating the plastic moment or modulus for any beam section is available?
Plastic Section Modulus about the element local y-direction
What is the main physical meaning of section modulus?
section modulus is a measure of the strength of a beam. The more the section modulus the more is the strength.
What is the reinforcement in beams?
Reinforcement is anything that provide additional strength to a beam. In a standard beam reinforcement refers to steel bars.
Where will you find the maximum shear stress in a beam?
The maximum stress occurs where shear load is maximum and maximum stress is at the center of the beam cross section if loaded in shear due to bending. It drops to zero at the top and bottom surfaces. The average stress is load divided by area ; maximum stress is dependent on shape of cross section and is 1.5 times load divided by area at the cross section center for rectangular cross section. For shear due to twist, max shear stress in the outer surface.

What is a prismatic beam?
A beam with a uniform cross-section.
What is use of calculating support reaction of a beam?
you will need that to calculate the strength and deflection of the beam, and also strength of the support itself
When is a beam said to be in uniform strength?
Bending moment is the same throughout the beam.
Why we use double reinforced section?
when section of the beam is restricted and the moment due to incoming load is not resisted by moment due to concrete then we have to provide reinforcement in compression zone also to take this extra incoming load

What is the purpose of strength reduction factors and why they are smaller for columns than beams?
the purpose of strength reduction factor is used to take into account the uncertainties of material strength, inaccuracies in the design equations, approximations in analysis, possible variations in dimension's of the concrete section and placement of reinforced, the importance of member of structure of which they are part, an so on. Column is designed stronger than beam it means during strong earthquake column member remain elastic so it can provide stability and strength of the stories above.
