What is engineering mechanics?what is rigid body what is maa length time and weight
Hello there,
Engineering Mechanics
Engineering Mechanics is a branch of physics that deals with the analysis of forces and their effects on bodies in motion or at rest. It involves studying how forces interact with materials and structures, and it is crucial for designing and analyzing various engineering systems.
Key Areas:
- Statics: Analyzes forces and moments on bodies at rest.
- Dynamics: Studies bodies in motion and the forces causing the motion.
- Kinematics: Focuses on the motion of objects without considering the forces involved.
-
Kinetics:
Examines the relationship between the motion of objects and the forces acting upon them.
Rigid Body
A rigid body is an idealized concept in mechanics where the body does not deform under the action of forces. In other words, the distance between any two points within the body remains constant, regardless of the forces applied. This simplification helps in analyzing and solving problems related to the motion and forces acting on structures or machinery.
Characteristics:
- No Deformation: The shape and size of the body remain unchanged.
-
Simplified Analysis:
Useful for simplifying complex problems in mechanics.
Moment of Inertia (I), Length (L), Time (T), and Weight (W)
-
Moment of Inertia (I):
-
Definition:
A measure of an object's resistance to changes in its rotational motion. It depends on the mass distribution relative to the axis of rotation.
-
Formula:
I=∑miri2I = \sum m_i r_i^2I=∑miri2, where mim_imi is the mass of the ith particle and rir_iri is its distance from the axis of rotation.

Definition:
A measure of an object's resistance to changes in its rotational motion. It depends on the mass distribution relative to the axis of rotation.
-
Length (L):
-
Definition:
The measurement of the extent of an object in one dimension. It is a fundamental parameter in geometry and engineering.
-
Units:
Typically measured in meters (m) or other length units like centimeters (cm) or millimeters (mm).
-
Definition:
The measurement of the extent of an object in one dimension. It is a fundamental parameter in geometry and engineering.
-
Time (T):
-
Definition:
The continuous progression of events from the past to the present and into the future. It is used to measure the duration of events or processes.
-
Units:
Measured in seconds (s), minutes (min), or hours (h).
-
Definition:
The continuous progression of events from the past to the present and into the future. It is used to measure the duration of events or processes.
-
Weight (W):
-
Definition:
The force exerted by gravity on an object’s mass. It is the product of the mass of the object and the acceleration due to gravity.
-
Formula:
W=m⋅gW = m \cdot gW=m⋅g, where mmm is the mass and ggg is the acceleration due to gravity (approximately 9.8 m/s² on Earth).
-
Units:
Measured in newtons (N) in the SI system, or pounds (lb) in the imperial system.
Conclusion
-
Definition:
The force exerted by gravity on an object’s mass. It is the product of the mass of the object and the acceleration due to gravity.
Engineering Mechanics involves analyzing forces and motions, rigid bodies are idealized models without deformation, and understanding fundamental concepts like moment of inertia, length, time, and weight is essential for solving mechanical problems.

Apart from Extremely expensive Universities like BITS what are best options in private univerties to do b.tech from IT, CS, MECHANICS, CIVIL
Hello Kartik,
Keeping your budget into account, i can find these particular college. Please keep a note that these fees are for general category.
1. Lovely Professional University - 8.52 lakhs ( for this you have to clear JEE main and LPU-NEST)
2. Delhi Technoogical University - 4 lakhs ( JEE main)
3. College of Engineering - 4 lakhs ( JEE main)
4. MNNIT Allahabad - 4 lakhs
can i get 8000 rank in 4months i have covered phy chem without mechanics and physical till jee main lvl not practiced ques only theory
Hello aspirant
Getting 8000 rank within 4 months with somehow preparation in JEE mains is not enough. You still have 4-5 months legft in your pocket. YOu should exceed more. If you want to come under 8K rank in JEE mains, then you should need to focus and give more time on solving previous year question papers, you must be more dedicated and consistent in solving more Questions from best reference books, you must practice more sums and must ficus only at your weak points.
Further, below are some of the best preparation strategy that you can follow if you want to lie within 8K rank in JEE mains :
Prepare A Well-laid Plan
Draft a daily schedule.
Prioritize the topics that require more time and relevant to the subject.
Stick to the routine and pay special attention to problems.
Get Hold Of The Syllabus
Manage your time effectively
Understand Basic Concepts
Before delving into JEE preparations, know the JEE syllabus and understand the basic concepts present in the syllabus.
Evaluate your knowledge on basic concepts.
Make notes on required topics.
Choose The Right Study Material
Further, follow and practice from the books mentioned below to ace yoru JEE mains preparation smoothly :
JEE Main Books Important for Mathematics
Trigonometry by S. L. Loney
Higher Algebra by Hall & Knight
Maths XI & XII by NCERT
Coordinate Geometry by S. L. Loney
Problems in Calculus of One Variable by I.A. Maron
JEE Main Books for Physics
Problems in General Physics by I.E. Irodov
Fundamentals of Physics by Halliday, Resnick & Walker
Concepts of Physics Vol I and II by H.C. Verma
Books for JEE Main Chemistry

CAN I SKIP MECHANICS FOR JEE ADVANCED???
I recommend you to solve DC PANDEY 500 selective question that will give ve you a rough idea
I think this will help you
sir i got 465 score in civil branch.can i get structure,soil mechanics or water resourse in any iit?
Dear aspirant,
As you have secured 465 score in civil branch , i would like to request to kindly mention your rank so that I will be able to guide you in an appropriate manner.
It's quite possible for you to get into lower IITs like Mandi, bhilai, gandhinagar, jodhpur but top iits would be a difficult bet. However various factors are considered while deciding the cut offs like number of candidates appearing in the examination, number of vacant seats in college, previous years cut offs and difficulty level of the paper.
For more information you can check out the link given below-
