Q1. Drow shear force diagram and bending moment diagram
Ans. 
Shear force and bending moment diagrams show the variation of internal forces along a structural element.
• Shear force diagram shows the variation of shear force along the length of a beam.

• Bending moment diagram shows the variation of bending moment along the length of a beam.

• Shear force changes sign at point of applied load, while bending moment is zero at point of applied load.

Q3. What is Water cement ratio?
Ans. 
Water cement ratio is the ratio of the weight of water to the weight of cement used in a concrete mix.
• Water cement ratio is a crucial factor in determining the strength and durability of concrete.

• A lower water cement ratio results in stronger and more durable concrete.

• The ideal water cement ratio varies depending on the type of concrete mix and its intended use.

• For example, a water cement ratio of 0.5 is commonly used

Q4. Father of mix concrete ratio?
Ans. 
The father of mix concrete ratio is Duff Abrams.
• Duff Abrams is known as the father of mix concrete ratio.

• He developed the Abrams' Law which is used to determine the water-cement ratio in concrete mix design.

• Abrams' Law states that the strength of concrete is inversely proportional to the water-cement ratio.

Q3. How to define the moment and shear connection s
Ans. 
Moment and shear connections are used in structural engineering to transfer forces between members.
• Moment connections transfer bending forces between beams and columns

• Shear connections transfer shear forces between beams and columns

• Moment connections can be achieved through welding, bolting, or a combination of both

• Shear connections typically involve bolts or welds to transfer the shear forces
