What type of material is reinforced concrete?
Concrete is composed of cement and other cementitious materials such as fly ash and slag cement, coarse aggregate made of crushed stone, fine aggregate such as sand, water, and chemical admixtures. In reinforced concrete, steel is introduced in to the concrete. In plain concrete, no steel reinforcement is introduced. Generally tensile and compressive strength is taken by reinforced concrete and only compressive strength is taken by plain concrete
A bent rod to resist shear and diagonal stresses in a concrete beam is called?
STIRRUPS
What is modular ratio in rcc?
In reinforced concrete construction, the modular ratio refers to the modulus of elasticity of concrete to that of steel. It is used in structural design calculations to determine distribution of stresses between concrete and steel in beams and columns.
What is full prestressing?
It is the one in which tensile stresses in the concrete are entirely obviated at working loads by having sufficiently high pre-stress in the member.
What is the advantages and disadvantages of pretensioning method of concrete?
pretensioning is the process of inducing reverse stresses to concrete prior to design loading so as to achieve slender sectins thereby reducing cost. disadvantages of pretensioning are losses due to slip, etc
What is reinforced concrete used for?
Actually concrete is not very good in tension therefore we have to introduce reinforcement which takes care of the tensile stresses. If we don't provide reinforcement, concrete will start showing cracks wherever tensile stresses overcome the concrete tensile strength.
What is internal equilibrium?
The internal equilibrium is a balance condition between internal forces and the commulative integrated stresses.
Why is annealing done?
Annealing can bring about ductility, soften material and it relieves internal stresses, This will improve the ability to work the metals when they are cold i.e. when bending steel in presses to make metal frames etc

How internal stresses are induced during quenching?
they simply ar. just by thermal and struxtural means

Difference between external and internal forces?
Internal forces are stresses and changes inside the material or body. External forces act independently upon an object.
