What is Engineering Mechanics & Strength of Materials ?





ENGINEERING MECHANICS

STRENGTH OF MATERIALS

Ø  In this we assume that the body is perfectly rigid (the type of material which doesn’t undergo any change in geometry of the body when load is applied).

Ø  In this we assume that the body is perfectly elastic (the type of material which undergoes change in geometry of the body when load is applied)

Ø  It deals with the study of external force & their effect on rigid body.

Ø  It deals with the effect of external force & their effect as internal resting force in bodies.

Ø  In rigid body, stress will develop but no strain.

Ø  In deformable bodies both stress and strain will develop.

Note- Concept of Ideal body or rigid body is hypothetical and it doesn’t exist.

WORKABILITY OF CONCRETE - AS PER IS-456-2000

WORKABILITY OF CONCRETE - AS PER IS-456-2000 The concrete mix proportions chosen should be such that the concrete is of adequate workability for the placing conditions of the concrete and can properly be compacted with the means available. Placing Conditions Degree of Workability Slump(mm) Blinding concrete; Shallow sections & Pavements using pavers   Very low In the ‘very low’ category of workability where strict control is necessary, for example pavement quality concrete, measurement of workability by determination of compacting factor will be more appropriate than slump ( see IS 1199 ) and a value of compacting factor of 0.75 to 0.80 is suggested. Mass concrete, Lightly reinforced sections in slabs, beams, walls, columns, Floors; Hand placed pavements; Canal lining; Strip footings     Low     25-75 Heavily reinforced sections in s...

What is characteristic strength of concrete in flexure ?

Blog By Er. Navneet Kumar What is characteristic strength of concrete in flexure ?  👉Characteristic strength of concrete is the value of strength of concrete below which not more than  5 % of test results are expected to fail.               It is denoted by fck.                                                           fck = fm- 1.65σ        Where fm= Target mean strength & σ = standard deviation. Note- 👉Concrete is designated by characteristic cube strength of concrete at 28 days. 👉No material is truly homogeneous , so strength of similar concrete varies in different testing. 👉For most of the engineering materials ,probability is symmetrical about mean and such a curve is called Normal Probability distribution curve.               ...
